[Zope] tree and expand_all

[Petr Knapek]

Hi all,
I have a problem with expand_all variable in tree which should expand
whole tree. When I post it 
(<A HREF="<dtml-var URL0>?expand_all=1">Expand</A>) 
it doesn't work. No change in tree rendering. On the other hand the
collapse_all works as predicted. 
Is anything wrong what I do or is it a bug? 
I use Linux with Zope 2.1.4

Thanks, Petr
