[Zope] dtml-tree status again

Hi! dtml-tree question again (ZopeTree is not suitable for now, because I want to build a tree from results of zsql methods) A little example to demonstrate my problem: <dtml-tree> <a href="&dtml-URL0;"><dtml-var id></a> </dtml-tree> Each link is pointing to the same page where the dtml-tree is, but when you click on any link, tree will lost its status, and it will be collapsed. Now that's what I don't want :) Version: Zope2.7.2 Lac
