Description:
In a tree selection listener method I update the tree itself and get a
nullpointerexception afterwards:

The problem seems to occur when a node is selected which is not present in the
new tree.
But the implementation should be so robust that there is no exception.
I do not reassign the bound root node object, instead I remove all child nodes
and add the new nodes to the root.
The tree definition is:
{code}
<rich:tree value="#{searchBean.suggestTree}" var="node" id="treeSuggest"
nodeClass="com.myapp.web.tree.EstabSuggestTreeNode"
nodeType="#{node.type}" selectionType="ajax"
toggleType="client" render="treeSuggest,detail"

<rich:treeNode type="neighborhood">
<h:outputText value="#{node.name}" />

<rich:treeNode type="estab" >

</rich:treeNode>
</rich:tree>
