I just had the same problem with the NullPointerException. I think it
is a facelet+myfaces issue. I had to add a "model" property to the
tree to stop the errors:
<t:tree
model="#{currentView.memberDialog.memberTree}"
value="#{currentView.memberDialog.memberTree}"
styleClass="availMembersTree"
expandRoot="false" />
