1.0.9 -> 1.1.1 : tree2 node state

[Dennis Byrne]

Using 1.0.9, the following maintains node state very well: 
node state is preserved even after users leave the view and 
come back.  After moving to 1.1.1, this only happens when the 
back button is pushed. Can anyone give me a high level idea 
as to what has changed?

<t:tree2 showRootNode="false" id="tree" 
   value="#{officeTreeBacker.tree}" var="node"
   varNodeToggler="t" clientSideToggle="false">
