folderbrowser.widget problem

Uldis

Hi

We have xECM integration where we use folder view widget (as described in OpenTextTM Extended ECM Platform Integration and Configuration Guide 20.4). Example code is simplified.

We recently updated our system to 20.4 (including xECM platform). 

Our existing widget code still works (in general). Except when you click on a document Name. Then there is js error (screen attached). 

<link rel="stylesheet" href="https://xxxx/img/csui/themes/carbonfiber/theme.css" >
<script src="https://xxxx/cs.exe/widgets?crossOrigin=true"></script>
<script>
 csui.setLanguage('en_US');
 csui.onReady2(["csui/lib/jquery", 'csui/integration/folderbrowser/folderbrowser.widget', ''],
 function ($, FolderBrowserWidget) {
 csui.require.config({
 config: {
// Back Buttoncontrol 
	'csui/integration/folderbrowser/commands/go.to.node.history': {
          enabled: true
      },
// Search From Here control 
	'xecmpf/utils/commands/folderbrowse/search.container': {
          enabled: true
      },
// Page Widget control
     'xecmpf/utils/commands/folderbrowse/open.full.page.workspace': {
         enabled: true,
         fullPageOverlay: true
      }
} });
 var folderBrowser = new FolderBrowserWidget({
    connection: {
        url: 'https://xxxxx/cs.exe/api/v1',
        supportPath: '/img',
        credentials: {
            username:'xxxx',
            password:'xxxx' }
        },
        start: { id: 932228 }, breadcrumb: false });
        
folderBrowser.show({placeholder: '#content'});
});
</script>

<div id=content></div>

In a different post in forums Ferdinand talked about a new approach to use folder view - csui/integration/folderbrowser2/folderbrowser2.widget
However this is not documented anywhere in xECM guides.
Should we now use folderbrowser2.widget approach in our integration (with version 20.4)? 
Should folderbrowser.widget still work with 20.4?
