rich:tree
Moving a file from one directory to another worked with my code in version 3.1.2.
<a4j:outputPanel ajaxRendered="true">
<rich:tree id="tree"
style="width: 300px;"
switchType="ajax"
stateAdvisor="#{ContentMB.imageTreeStateAdvisor}"
nodeSelectListener="#{ContentMB.selectImageNode}"
changeExpandListener="#{ContentMB.expandImageNode}">
<rich:recursiveTreeNodesAdaptor id="dir"
roots="#{ContentMB.imageRoots}"
var="dir"
nodes="#{dir.directories}">
<rich:treeNode dropListener="#{ContentMB.moveFile}"
dropValue="#{dir.path}">
<h:outputText value="#{dir.label}" styleClass="text" />
</rich:treeNode>
<rich:treeNodesAdaptor id="file" nodes="#{dir.files}" var="file">
<rich:treeNode dragType="#{file.suffix}"
dragValue="#{file}">
<h:outputText value="#{file.label}" styleClass="text" />
</rich:treeNode>
</rich:treeNodesAdaptor>
</rich:recursiveTreeNodesAdaptor>
</rich:tree>
</a4j:outputPanel>
Since I have upgraded to 3.1.3 CR4, I'm getting the following error:
java.lang.IllegalStateException: No tree element available or row key not set!

It seems to me, that the bugfix in RF-980 doesn't work any longer.
Thanks in advance,
Christian
