[Zope] tree tag and the URL attribute

[Florian Schuler]

Hello List,

I=B4ve made a dtml-method with a tree tag and a SQL method. It works =
fine.

My problem is that i want to add a HTML form variable to the link of =
the
plus and minus buttons.

For example:
---------------|
=09
`=B4
<A NAME=3D"1"
HREF=3D"projekt_mailingliste_html?tree-e=3DeJyLVneEAo9QT1t1HQXDWAAwLQSv#=
1
&myVar=3DmyValue"
=09
--------------

I tried the url attribute of the tree tag but nothing happend.
<dtml-tree id=3DmyID branches_expr=3DmyExpr url=3DmyURL>
.
.
.
</dtml-tree>
Is it possible to change this link ? How ?

Thanks in advance
