IllegalArgumentException: Row key is illegally formed

[user1234]

In my application i am using a tree like this

<rich:tree switchType="ajax"
 toggleOnClick="true" reRender="ajx,pageBodyContainerPanel"
 id="leftMenu" nodeSelectListener="#{menutree.nodeClick}"
 value="#{menutree.treeNode}" var="item" highlightedClass="highlightedTreeNode"
 selectedClass="selectedTreeStyle" iconCollapsed="/Images/plus.gif"
 iconExpanded="/Images/minus.gif">



 </rich:tree>

java.lang.IllegalArgumentException: Row key is illegally formed: 6:2:2:2

Why it is showing??
And another question can i execute a javascript after completing "nodeSelectListener" ??

1) could you provide full sample in zip (with sources and libs)?

2) yes. Use oncomplete attribute.
