[Zope] Tree tag

[Katrin Kirchner]

Hi everybody!

I'm having a problem with the tree tag. I have a page where I want to
show all postings of 7 Confera Topics. So far I can show the different
trees of the Topics but the page raises an error message when I want to
expand any of the trees. Therefore I want to show the page with the
trees already expanded. But whatever I tried, the trees aren't shown
expanded.

I've tried the following commands:

<!--#call "REQUEST.set('expand_all', 1)"-->
<!--#call "REQUEST.set('expand-all', 1)"-->

and I've tried to put expand-all or expand_all in the tree tag. But
nothing worked. When I try to put expand-all in the tree tag, it says
it's not a valid argument.

Is there anyone who can tell me how to have the trees shown expanded?

Thanks in advance

Katrin
