[Zope] dtml-tree (urlparam)

[Ulla Theiss]

Dear list,

many thanks for the link to a little bit more documentation of 
dtml-tree. Unfortunately the parameter of interest (urlparam - Since 
Zope 2.2??) is not mentioned there.

Meanwhile I found in the "Zope-Bible" (Chapter 4, Page 115): "The use of 
this attribute [urlparam] is somewhat limited because Zope simply passes 
along whatever string you specify as the value for the urlparam 
attribute. Expressions, and therefore the dynamic insertion of 
variables, are not possible with this attribute under the current 
version of Zope."  ;-(

The first question is clear now, but the second one becomes more and 
more important:

Does anybody have an idea to work around the problem?

Again, many, many thanks in advance,
Ulla.
