New in 21.1: The new CAPI.ExecN Oscript command

New OScript for 21.1

There is a new CAPI.ExecN command special for Postgres operations.

Oscript, the final frontier. We write the year 2021 and the OScript universe is going to expand. The newest member is CAPI.ExecN.


Bulk Postgres operations are slow. There is a new implementation of CAPI.ExecN, which fixes this. But there is no free beer in the universe. This new implementation exposes Postgres SQL weaknesses (throws SQL errors).

As for 21.1, this is an experimental feature. IN 21.2, it will be activated by default.

For all the explorers in the world, this feature has to be actiated manually in 21.1.

Remove Commands from Nodestable etc in the smartUI SDK

Command is Gone

From time to time you’ll need to remove commands from the widgets, like the nodeslist widget.

The magic spice is setting up a blacklist on the masks.js files during the initial phase:

  config: {
    'csui/widgets/search.results/toolbaritems.masks': {
      'mycustomer': {
        'otherToolbar': { blacklist: ['Properties', 'permissions'] },
        'inlineToolbar': { blacklist: ['Properties', 'permissions'] }

There are several possibilities to do that.

1, The approved way

The approved way is to configure smartUI before its initialized from OScript.

This can be done by overriding the GetDynamicConfiguration in your base smartUI module (the one with the csuiextension orphan) like:

override function Assoc GetDynamicConfiguration(Object prgCtx, Record request)
    List blacklist = { "Copy", "Move" }
    return assoc{
      "csui/widgets/nodestable/toolbaritems.masks": assoc{
        "basecsui": assoc{
          "tableHeaderToolbar": assoc{ "blacklist": blacklist },
          "inlineToolbar": assoc{ "blacklist": blacklist },
      "csui/widgets/nodestable/headermenuitems.masks": assoc{ 
        "basecsui": assoc{ "blacklist": blacklist }     }    }

Here in this example, the toolbaritem.masks and the headermenuitem.masks are set up with our magic spice (a blacklist containing all the signatures of the commands not desired). This will remove the “Copy” and “Move” commands from the list of commands permanently. And permanently means, this will survice a Page Reload.

2. The ugly way (but also surviving a Page Reload)

The ugly way is a way is the standard OpenText Way of overriding app.html and configuring the blacklists by yourself. Lets take a look at the app.html (found at ../core/module/csui/html).

Here is an example on a windows server:

Where to find app.html
app.html - the head

In the upper part you can see the csui.require calls. At the top you’ll notice a csui.require.config call, where you can put our magic spice (see above).

The disadvantage is, when you override app.html (directly or by using htmlmap) then you’ll have to check, if any future OpenText patches will override the app.html also.

BUT: If you override app.html, you can take advantage of this for example by implementing a permanent footer, which is always drawn at the bottom. You cannot do that with pure smartUI tools.

Here is an example of a permanent footer in the body part of the app.html.

Multiple usages of app.html - the body

3. The force way

There is also a brutal way to remove commands without that configuration of app.html. This requires

  • a widget or a command to do the removal
  • a couple of js lines

But on the other hand, this is the way which allows easy recovery of the command by doing a simple refresh of the page.

Here is a demo case (a wild version of the hello widget from my training installation). This is a widget with some demos and a new inserted button to delete a command.

a very chaotic demo

Behind the button are some js lines of code, which will remove the Copy-Command. Actually, the lines var b=commands.get(“Copy”); and commands.remove(b); do the job.

You will have to require /csui/utils/commands unter commands to use this two lines.

Two lines to decide the fate of the copy command.
Two Javascript Lines will decide the fate of the copy command

Lets see the initial command set. The Copy Command is here as usual.

Copy command lives

After the red button is pressed in the then the Copy Command is gone:

Copy Command is gone

We simply deleted the Copy command from the list of commands. This means, a simple Refresh will restore it.

Have much fun on playing around with commands!

smartUI in practice: SMART TOOLS(4) –Direct Access of Renditions – Technical

smart tools
Cell Renderer


Last week, we discussed a possible implementation of the direct access to renditions. This icon is drawn an a document, which das renditions at the newest version. Clicking on that icon opens a panel which lets the user select one of the renditions to download or delete.

Direct Access Rendition

Selecting one of the renditions will download this rendition or (if permissions allow it)( delete the rendition.


The whole thing is based on a cell renderer. This relies on the extension point node.state.icons which is (as always) declared in the extensions.json file:

"csui/controls/table/cells/node.state/node.state.icons": {
"extensions": {
    "csuia": [

This declaration points direct to the appropriate node.state.icons

function (RenditionView) {
'use strict';
return [ { sequence: 60, iconView: RenditionView } ]; });

This basically declares the required view named “rendition.view.js” as responsible to draw the icon at sequence position 60.

This is the template used for the view.

Cell renderer Template

The image is drawn cia the css seen above.

Encapsulating this inside a link allows to make the svg clickable.

Enable the direct access

The first point is the decision, if the cell renderer is to be drawn or not. This is a static method at the view, returning true or false. We dont have ony clue if the nodeid does have a rendition at the newest version, so we have to implement a new REST command at the server to get the information. The REST must be called synchronously.

the static enable function

This is done via a simple XMLHTTPRequest. If the result is true, we return true and store the number of each rendition types at the node in the prototype for further processing.

Then lets take a look on the events:


This means, a click on the class of our link in the template will call onOpenView. Before we look at that, look at this in the templateHelpers:

Open the Panel after the click

Remember, we got the number of each rendition types from the server? We want tzo display these numbers as a tooltip over the icon, so this is the way to formet the output string. A note to the knights of the holy JS-grail: Referencing this.__proto__ instead of finding the prototype via object maybe depreciated, but at least its also in ECMA 6! So nowadays its a valid method.

When we click on the icon, we want to open a DialogView from the sdk toolkit with an embedded view (SelectView) in the method onOpenView:


Before we open this view, we call the server to get the renditionlist of this node via XMLHTTPRequest. If we get the list (status=200) we intiantiate the view (selview1) and display the DialogView containing the instantiated view at the bin_modal default EL anchor.

Then lets show this region and store a event handler (string “submit”), which is listening on the view selview1 for that string. If it receives that string, the DialogView is closed.

Next week, we’ll examine the SelectView.

smartUI in practice: SMART TOOLS(3) – Renditions

smart tools

In SMART TOOLS renditions are also build in the properties manager of smartUI. Renditions can be displayed by selecting renditions on the pull down menu, just like Multilingual Metatata in my last post.

The main menu

Rendition Main Panel

Next, the main panel of renditions is displayed. The renditions of the newest version or the latest 5 versions will be displayed.. A Rendition can be downloaded, deleted, replaced or (if configured) with “View as Webpage” be seen.

Rendition Commands

If there are a lot of versions, a starting version can be selected. Then this version and the last 5 versions with all renditions will be displayed.

Ascending or descending sorts on versions can be done by clicking on Versions.

Interesting is the “View as Wewbpage” function. This is a build in function in the Content Server, so it can also be used to see the contents of any renditions in the classic UI and in a separate window.

view as webpage display

A rendition can also be downloadeed by clicking on the down.arrow icon. This will normally download the file as setup by the users browser. If the rendition is a PDF and print.js (a standard extension in browsers) is activated, the the pdf can also be displayed directly.

A list of renditions can also be printed. This is a nice addition to help you to get an overview.

Rendition list

Direct Access Renditions

For a direct access to renditions, I also added a cell renderer to be displayed, if the newest version of the document has a rendition.

This is a little svg icon displayed directly in the list of documents.

Cell Renderer

The little icon can be clicked and then a list of renditions belopnging to this document is displayed.

Direct Access Rendition

From this panel, a rendition can be selected and downloaded. If the user has proper permissions, he can also delete the rendition selected. Also a printed list (see above) can be made at this point.

Sorting in ascending/descending versions can be done by clicking on the Arrow in the “Vers” columnn.

Because this direct access requires a lot of calls to the server, this feature can be switched off at the Admin Pages of smartUI.

Add Rendition Command

Additionally, there is also one command required, the “Add Rendition” command. The “Make Rendition” command is not implemented, because this requires local admin rights, something which should be rare.

This command can be issued at any document directly from the list of documents

Addrendition command

Commands are usually displayed in two locations, the Headertoolbar (above) and the Toolbar (below)

Command in Toolbar

Adding a rendition means, selecting one of system defined rendition types and a file beeing intended as the rendition. If the selected rendition type does not exist on that document, then the file is uploaded and used as a rendition.

Add Renditions - Panel

Next week, we dive more in the direct access of renditions and the Pros and Cons of that technique.

smart tools

Using OpenText Content Server as as developer, you have to face it sooner or later: Write an application in smartUI. This will give you a lot of experience for smartUI projects, especially on the Cost/Times/Materials base.

I did chose to build a product called SMART TOOLS with Renditions and Multilingual Metadata Support. Product means, it can be sold by other OT partners as well.

This is a multipart post. Today we talk about the basics of the application running in Content Server 20.2. Additional posts will explain the usage and some technical aspects


SMART TOOLS includes these features:

  • Adds support for Multilingual Metadata to smartUI
    • Automatic Translations for the multilingual data using Microsoft Azure REST service (as nobody speaks all languages on this planet)
    • Add print lists (to get a list of the data entered for editing)
    • Add/edit mlm data directly
    • Integrated in the standard nodelist widget using the property manager
  • Adds support for Renditions
    • List all Versions and Renditions
    • Use “view as webpage” as a base viewer
    • Download renditions
    • Delete renditions
    • Replace renditions
    • Add Renditon as command
    • A cell icon marks all documents in the document list having renditions at the newest version. Clicking on the icon will open a window to show all renditions. Download or delete a rendition.
  • Adds configuration support for the javascript client software from the Admin pages. Critical things like MS Rest API key can be protected by sending this things at the page creation time to the client.

The SMART Tools are build for Content Server 20.2. A a considerable amount of new REST services also to be implemented in the Content Server.

The Integration

Integration is simply direct in the nodelist widget using the property manager.

Open the property manager

By clicking in the first icon in the list, the property manager opens.

Renditions and Multilingual Metadata

The panels adressed by this menu are the multilingual metadata panel (with the two fields Name and Description) and the rendition panel. Here you see the mlm panel with the autotranslate Icon (the globe at the right).

mlm main panel

This is the rendition panel which shows all renditions attached to all versions.

Renditions main panel

Language support

The SMART TOOLS support a couple of UI languages like

  • English
  • German
  • French
  • Spanish
  • Italian

This is one example on the multilingual metadata dialog using German, French and English.

The nls feature of smartUI is nice, isn’t it? I even tried it (experimental) for Arabic, and it worked!

Lets go more in detail in the next posts, as this here is intended to be a simple overview.

Next week I will describe the multilingual metadata support of smartUI

Config Settings send to a smartUI Module

There are several possibilities to set the configs from the base OScript Module. The most interesting is the method of setting the configs via Oscript. The complete list of the possibilities is_

  • When you visit a mode or get a children
    • Implement “fields” and/or “expand” in the appropriate CSNode.
    • Use the date from data.(
  • When the Widget is created
    • Implement an REST service which will give you the data
    • Load the data on the first widget creation and cache it with a permanent model factory in the context
  • When the page is loaded
    • The CSUI::Extension::GetDynamicConfiguration method in OScript has normally this entry
function Assoc GetDynamicConfiguration( Object prgCtx, Record request )      
return Undefined

Overwrite it with your desired configuration (here only the enableAppleSupport is displayed for clarity):

 function Assoc GetDynamicConfiguration(

        Object      prgCtx,

        Record      request )      
Assoc       basicAppData
Assoc       config 

        Boolean     enableAppleSupport


        // changes in admin page should be reflected immediately by every thread

        settings = $WebAdmin.AdminUtils.GetSmartUISettings( prgCtx )
    if ( IsFeature( settings, "enableAppleSupport" ) && IsDefined( settings.enableAppleSupport ) )

        enableAppleSupport = settings.enableAppleSupport



    config = Assoc{ 
     "csui/utils/commands/": Assoc{ "enableAppleSupport": enableAppleSupport },

    return config


The returned assoc consists of a requirejs module name containing an assoc with the config values.

In your js module (here csui/utils/commands/ add this line

var config = _.extend({
rewriteApplicationURL: false,
enableAppleSupport: false,
appleNodeLinkBase: 'x-otm-as-cs16://?launchUrl=nodes/'
}, module.config());

Then the config is avaliable in your js module and can be used like

var iOSEnabled = config.enableAppleSupport

Nice, isn’t it?

Practical smartUI: Reading complex categories on the Content Server Side

Normally, when building REST Services for smartUI, you’ll have to read complex attributes from categories to send them for display to a widget.

Lets use this example

A complex Category with 4 Sets and Table Key Lookups
A complex category with multible sets and table lookups (click to enlarge)

In your REST handler, you r task would be to get the values of the category attached to a node, read them and send them to the client using REST.

In this writing, we’ll focus on the “Read them” part. Our trick is

object  LLNODE = $LLIAPI.LLNodeSubsystem.GetItem(node.pSubtype)
result = LLNODE.NodeCategoriesGet(node)

Thos gives us all Categories connected to a node.

When we receive the REST call in ther server handler, we should do

  1. find the node id of the the object to examine.
  2. find the categories attached to this node (Red Arrow in the Screenshot)
  3. iterate over all categories and get the attributes we want. This is based on
    1. the attribute definitions (Green Arrow on the Screenshot)
    2. the attribute values (Yellow Arrow on the Screenshot)
  4. if you encounter a set (-18 as attribute type), you also will have to iterate over the set (Red Rectangle)
Get the Values of a complex category
The REST Handler to get the Values of a complex category

Lets take a look on the Values of a single Category. They are inside an assoc with one entry per attribute id.


The Value list in CSIDE
The value list in CSIDE

Now you are almost done. Put a switch construct to get all values of the attributes on which you are intersted and get them out of the fdata assoc. The Value is found in the fdata assoc of the n-th Category unter the content of the first Value entry. Then we have to pick the attribute id where we find the content of the attribute in the first Value entry.

The Str,ValueTostring typecasts the output to be a string. So when we finished the job, we’ll see in the entry event.eventcycle the value of the attribute with the name “EventCycle”.

Get the attributes of interest
The switch construct to get the attributes of interest

The only thing to do is put the values in assocs and send them to the smartUI widget under the main clause “events” in the JSON array

Sent the values back
Send the values back. Support 200 (ok) and 500 (error) as status code.

So you see, Categories are no Monsters. They are quite user friendly. Using the same mechanism, you can even update complex Categories with one REST call.

Happy smartUI programming.

Quick List of all Categories and Attributes in a Content Server

Looking for a quick list of all Categories and Attributes configured in a Content Server? Tired of browsing the Categories Volume? Want to see all attrobutes and their IDs in a list?


Simple use this line as your URL

<server><OT base><cgi>?func=attributes.dump

(p.ex. http://myserver/myContentServer/cs.exe?func=attributes.dump)

This will return this list:

The attribute.dump output
The attribute.dump output

Although this is a screenshot from a Contentserver 16.2.6, you can use this command at least back to Version 10.5.


Using the CSIDE Code Generation Wizard (1) – Create WebNode Action automatically

In the newer versions of CSIDE, you’ll find a code generation wizard, which writes code snipets for standard tasks automatically.

You can call this Code Generation wizard by clicking on the right mouse button.

Call of the Code Generation Wizard

Next, the Code Generation Wizard gives you a list of all templates, which can be used for the code generation. The amount of templates can vary from CSIDE version to CSIDE version.

List of all Templates to be used for the code generation

When you click on a template, you’ll get further info’s on the template. The amount of info’s can vary from template to template.

Infos on the template

Here in this post, we are using the “Create WebNodeAction” Command. Refer to future posts on examples of the other templates.

A WebNodeAction is a command, which is executed against a node by issuing a WebNodeCommand (in Contenxt/Node or other menus). For example, the “Open” command in a node menu is a WebNodeCommand, which issues the action for opening the node content.

After selecting “Create WebNodeAction”, we must provide two additional definitions.

Additional Infos to provide

First, we must select the package to put this command in. We simply select DELIVERER (the name of our module), but in practical situations, you should select a proper package.

And the name of the command has to be provided. After clicking “Finish”, a file with the name “MyTestCommand.os” will appear in the first level of our OSPACE.

The Command is generated as .os file

When you open the newly created file, you’ll see a complete command definition.

Command Definition Part 1

The fEnabled is set to true. The fWebScript has the default name of “mytestcommand.html” and there is an empty list of fPrototype.

Change the name of the fWebScript to the name you want. Add the Webingo parts of the commands output in this fWebScript.

If you use special parameters in the request, setup the proper fPrototype list.

The _Nodetypes() returns an undefined List, which should be changed immediately to reflect the node subtypes for which the command should be valid.

Command Definition Part 2

There is even a _SubclassExecute stub generated automatically. Add the action code to be executed in this _SubclassExecute stub.

Optional: Connect this WebNodeAction with a WebNodeCommand in a context or node menu or somewhere in the GUI to make it accessible for the end-user.
