How to use rich:treeNodesAdaptor programmatically?

[grundor]

Hello,

I am trying to programmatically create a rich:tree from a model stored in the database. The tree is nested within a rich:panelMenuGroup. The panelMenu itself is dynamically created.

Here is the snippet of xhtml page source that shows the panelMenu binding:

 <h:form id="navform">
 <rich:panelMenu id="navMenu" binding="#{navigationAction.navMenu}">
 </h:form>

Here is the getNavMenu implementation and code where the tree creation is attempted in my Seam component:

 public HtmlPanelMenu getNavMenu() {

 if (navMenu != null)
 return navMenu;

 return buildNavMenu();
 }

 private HtmlPanelMenu buildNavMenu() {
 List<Menutab> menutabs = sportHome.getInstance().getMenutabs();
 navMenu = new HtmlPanelMenu();
 navMenu.setExpandSingle(true);

 for (Menutab tab : menutabs) {
 HtmlPanelMenuGroup group = new HtmlPanelMenuGroup();
 String label = tab.getMenutabCaption();
 group.setLabel(label);

 String name = "navgrp_" + tab.getMenutabId();
 group.setName(name);

 // Add pre-defined items
 if (tab.getMenutabType() == MenutabType.MENUTAB_TEAMS) {
 addTeamTree(group, tab.getSport().getSeasons());
 }

 navMenu.getChildren().add(group);
 }

 return navMenu;
 }

 private void addTeamTree(HtmlPanelMenuGroup parentGroup, List<Season> seasons) {
 HtmlTree teamTree = new HtmlTree();
 teamTree.setSwitchType("client");

 HtmlTreeNodesAdaptor seasonAdaptor = new HtmlTreeNodesAdaptor();
 seasonAdaptor.setNodes(seasons);
 seasonAdaptor.setVar("_season");

 HtmlTreeNode seasonNode = new HtmlTreeNode();
 seasonNode.setData("#{_season.seasonId}");
 seasonNode.setIcon("img/season.png");
 seasonNode.setIconLeaf("img/season.png");

 HtmlOutputText text = new HtmlOutputText();
 text.setValue("#{_season.seasonName}");

 seasonNode.getChildren().add(text);
 teamTree.getChildren().add(seasonNode);
 parentGroup.getChildren().add(teamTree);
 }

So basically I am dynamically creating a MenuPanel control, and within one of the MenuPanelGroups I am attempting to create a tree control using HtmlTreeNodesAdaptor.

The panelmenu is displaying just fine, but the tree control does not display using the above code. Can anyone comment on whether I am on the right track? Is it valid to use HtmlTreeNodesAdaptor in this way?

Regards,

Another option I can see is to simply embed an a4j:include within the PanelMenuGroup. My included xhtml would then use the rich:treeNodesAdaptor and recursive versions to create the tree.

It seems to work fine when I statically code the include into the PanelMenu, but when I try it in code it never shows up:

 HtmlPanelMenuGroup group = new HtmlPanelMenuGroup();
 String label = tab.getMenutabCaption();
 group.setLabel(label);

 String name = "navgrp_" + tab.getMenutabId();
 group.setName(name);

 Include myInclude = new Include();
 myInclude.setViewId("/layout/navtree.xhtml");
 group.getChildren().add(myInclude);

Unfortunately I can't code it statically as I need to allow the user to reogranize the order of the panelmenugroups.
