XPages extlib oneui layout - How to add placebar actions dynamically

Question

I want to add actions dynamically in PlaceBar (extlib oneui application layout).

We have couple of urls stored in some configuration documents. Based on these URLs I want to create Container node having Basic Child nodes in it. Every child node use one URL from list. How I can create container node and add child nodes to it dynamically? any sample SSJS/Java/CSJS code for this?

Thank you..

Answer 1

Have a look at the Repeat Node (xe:repeatTreeNode) which is described in the XPages Extension Library book on page 245.

Here's a very simple example (taken directly from the book):

<xe:repeatTreeNode var="val">
   <xe:this.value>
      <![CDATA[#{javascript:return [
        ["Home","home"],
        ["Domino","domino"],
        ["OneUI","oneui"]
      ];}]]>
   </xe:this.value>
   <xe:this.children>
      <xe:basicLeafNode>
         <xe:this.submitValue><![CDATA[#{javascript:return val[1]}]]></xe:this.submitValue>
         <xe:this.label><![CDATA[#{javascript:return val[0]}]]></xe:this.label>
      </xe:basicLeafNode>
   </xe:this.children>
</xe:repeatTreeNode>

Thank you for the quick reply. This is very useful information for me.

Another way I found out based on XSnippet code and some reverse engg. from java code in xpage as follow :

var oneui = getComponent("applicationLayout1");
var uiConfig = oneui.getConfiguration();
var containerNode:com.ibm.xsp.extlib.tree.complex.ComplexContainerTreeNode = new com.ibm.xsp.extlib.tree.complex.ComplexContainerTreeNode();
containerNode.setLabel("Cluster Applications");

var docAppProfile = docColl.getFirstDocument();
while(docAppProfile != null)
{
    var children:com.ibm.xsp.extlib.tree.complex.ComplexLeafTreeNode = new com.ibm.xsp.extlib.tree.complex.ComplexLeafTreeNode();
    children.setComponent(oneui);
    children.setLabel(docAppProfile.getItemValueString("appTitle"));
    children.setHref(docAppProfile.getItemValueString("appURL"));
    children.setImage(docAppProfile.getItemValueString("appLogoThumb"));
    containerNode.addChild(children);

    children = null;
    var tempDoc = docColl.getNextDocument(docAppProfile);
    docAppProfile = null;
    docAppProfile = tempDoc;
}
uiConfig.addPlaceBarAction(containerNode);

This is sample code only. Converted this is into java code and serialized to improve performance and load it only once in application.

Thank you again for help.
