Tree2 preserveToggle and server side

[Ryan Wynn]

I hava a tree2 component with server side state saving and
preserveToggle = true.  When the view that contains the tree is left
and returned to the tree does not retain expanded state but returns to
a collapsed tree.  Any ideas what I could be doing wrong?  Is this
expanded state management supported in server mode?  I am using
myfaces 1.1.1.

Thanks,
Ryan
