Hi

I am trying to create a rich:tree component.
Find the code snippet below.

<rich:tree
nodeSelectListener="#{treeBean.processSelection}"
ajaxSubmitSelection="true"
switchType="ajax"
changeExpandListener="#{treeBean.processExpansion}"
adviseNodeOpened="#{treeBean.adviseNodeOpened}"
id="tree"
ajaxSingle="false"
adviseNodeSelected="#{treeBean.adviseNodeSelected}"
value="#{treeBean.rootNode}" var="item" nodeFace="#{item.type}">

<rich:treeNode id="#{item.id}" type="node" onclick="nodeClick(#{item})" iconLeaf="/treemanager/images/parent_norm.gif" icon="/treemanager/images/parent_norm.gif">
<h:outputText value="#{item.name}" style="font-size:8pt;"/>
</rich:treeNode>

<rich:treeNode id="#{item.id}" type="leaf" iconLeaf="/treemanager/images/orange.gif" icon="/treemanager/images/orange.gif">
<h:outputText value="#{item.name}" style="font-size: 8pt;"/>
</rich:treeNode>

<rich:treeNode id="#{item.id}" type="next" iconLeaf="/treemanager/images/next.gif" icon="/treemanager/images/next.gif">
<h:outputText value="#{item.name}" style="font-size: 8pt;color:blue"/>
</rich:treeNode>

<rich:treeNode id="#{item.id}" type="prev" iconLeaf="/treemanager/images/previous.gif" icon="/treemanager/images/previous.gif">
<h:outputText value="#{item.name}" style="font-size: 8pt; color:blue"/>
</rich:treeNode>
</rich:tree>

When I try to give the id as EL, am getting exception as mentioned below.
(It works fine with a static one)

Can't we dynamically create Id for richfaces components or the way I am doing is wrong?

Can any one clarify it?

Thanks in advance
