Programatically (server side) select a node in rich:tree

[mosheelisha]

I have a tree with a nodeSelectListener:

<r:tree id="myTree" value="#{myTree.rootNode}" var="treeVar"
 nodeFace="#{treeVar.type}"
 nodeSelectListener="#{myTree.processSelection}" >
 .
 .
 .
</r:tree>

In the processSelection method I extract the selected value into a data member.
In some cases I would like to change the selected node in the server side and that the new selected node will be visibly selected in the tree so the user will know which node is currently selected.

How can this be done?

Take a look at the TreeStateAdvisor interface.

This interface will tell the tree which nodes are open and which node is selected.
You have to bind your implementation

<rich:tree ...
 switchType="ajax"
 stateAdvisor="#{myBean.myTreeStateAdvisor}"
 ...

Thank you. That what I was looking for.

Because I don't need the opened node control I used the tree's adviseNodeSelected property and attached it to this method:

public Boolean adviseNodeSelected(UITree uiTree) {
 Boolean advise = null;
 if (isAdviseNodeSelect()) {
 setAdviseNodeSelect(false);
 advise = Boolean.TRUE;
 }
 return advise;
}
