TreeNode Selection InvalidArgumentException

[dgbarber]

I just upgraded to Primefaces 2.2. My p:tree now throws an InvalidArgumentException when a selection is made. It worked with V2.1.

Here is my test code:

<p:tree nodeSelectListener="#{treeBean.onNodeSelect}"
value="#{treeBean.model}"
var="node"
selectionMode="single"
selection="#{treeBean.selectedNodes}"
update="testTextPanel">
<p:treeNode>
<h:outputText value="#{node}"/>
</p:treeNode>
</p:tree>

The "selectedNodes" property in TreeBean.java is declared as:

private TreeNode[] selectedNodes;

The nodeSelectListener is never hit.

The traceback is:

Your selection should be a single TreeNode instance not an array.
