Re: selectBooleanCheckbox not checked after valuechange, why?

Ah, tree2 got lucky! ;-)
Then it's perhaps the right time to either make it more robust (my preference, tree2 is used a lot and is a very cool component - when it works) or move it to Sandbox because of all current issues. Meanwhile, perhaps people now of robust tree components with similar features?

tree2 was created at a time, when there was no sandbox

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...?
