Why : Not displaying the rich:tree?

[allforjava]

Dear Team,

I need to display the resultSet entries as tree nodes. However it is throwing the exception as:
"javax.faces.FacesException: javax.el.PropertyNotFoundException:
/ILT.xhtml @25,104 nodes="#{issue.resultList}":
Property 'resultList' not found on type org.domain.Portal.entity.Issues"

Is it the way I'm using the resultList, wrong?

Code ILT.xhtml

<rich:panel>
 <rich:tree id="tasksTree" switchType="client">
 <rich:recursiveTreeNodesAdaptor roots="#{issuesList}" var="issue" nodes="#{issue.resultList}">
 <rich:treeNode icon="/img/down.gif">
 </rich:treeNode>
 </rich:recursiveTreeNodesAdaptor>
 </rich:tree>
 </rich:panel>

The issuesList returns the List of issues fetched from database, extended the EntityQuery from Seams Framework.

Thank you in advance!

Does the roots for recursiveTreeNodesAdaptor needs only collection? coz I have a single root node. And the way issueList used as root, is it a right way (It sounds silly, I'm confused).

With treeNodesAdaptor the nodes are generated. However I ned to use recursiveTreeNodesAdaptor for further sub-trees.
