Mmmm, this tree2 component seems to have more "sandbox" than “tomahawk" character, it's a very easy to run into issues. (suffices to do a find for "tree2")
I though my last problem was bypassed (clientSideToggle doesn't work), but when I try to come back at the same page a second time, I always get a NPE. 
So, to be clear, the scenario is:
Portal page -> Page with Tree -> 'OK' brings one back to teh portal page // this goes fine now (only with clientSideToggle="false" otherwise tree state is messed up) 
& Then:
Portal page -> (same Use Case selected) Same Page with Tree // this always causes a NPE on the tree2 component.
I first thought: there'll be a left-over (proper cleanup?) in the session/resquest, so have logged all "request params" & "session attributes" but there wasn 't anything inside referencing a tree. (except jsf_tree_64 but that 'll be for smth else as it was already in the request in the first half of the scenario) 

The internal error produced is this:
Anyone an idea...?
