I am trying to use a tree to allow users to reorder nodes using drag and drop. So far, I have everything working but tree re-rendering / refreshing.

A simplified version of the code demonstrating my issue is listed below:

<a4j:form ajaxSubmit="false" id="treeForm" reRender="theCategoryTree">
 <a4j:log/>
 <rich:dragIndicator id="indicator" />

 <a4j:outputPanel id="treePanel">
 <rich:tree id="theCategoryTree" style="width:300px"
 nodeSelectListener="#{categoryTreeEditView.processSelection}"
 reRender="treePanel"
 ajaxSubmitSelection="true" switchType="ajax"
 value="#{categoryTreeEditView.tree}"
 adviseNodeOpened="#{categoryTreeEditView.isNodeExpanded}"
 var="category"
 binding="#{categoryTreeEditView.categoryTreeBinding}">
 <rich:treeNode dragIndicator=":indicator" dragType="node"
 ajaxSubmitSelection="true"
 dragValue="#{category}" dropValue="#{category}"
 acceptedTypes="node"
 dropListener="#{categoryTreeEditView.processDrop}"
 reRender="treePanel">
 <h:outputText value="#{category.name}" />
 </rich:treeNode>
 </rich:tree>
 </a4j:outputPanel>
 </a4j:form>

When dragging one node to another, a move / reorder operation will occur. I can see all of this taking place in my application server logs. But, the tree component does not reflect the change. If I click on another tree node after performing a drag operation, the tree does refresh and the tree reflects the correct state.

I did notice if I set ajaxSubmit="true" the auto-refresh of the tree does function. But, ajaxSubmit="true" breaks other parts of my application (ultimately I need to support file upload and ajaxSubmit="true" definitely precludes this. I also have the option of using a jenia4face popupFrame to create a place to perform file upload, but again ajaxSubmit="true" breaks the popupFrame).

Is there a way to cause a rich tree refresh after a drop operation?

Thanks for any suggestions.
