[Zope-dev] Custom dtml tag ... parameters not evaluated

[Romain Slootmaekers]

Yo,
I'm trying to create a custom dtml tag, and after the How-to on this
(http://www.zope.org/Members/z113/1) that in itself posed no problem: easy
as pie. The problem I'm having with the tag is that parameters are not
evaluated. for instance (my tag's name is 'aa')

<dtml-let y="someValue">
<dmlt-aa role="y" ...> ....</dtml-aa> 
</dtml-let>


gives me in the code:  role=="y" 
while I want it to be "someValue", playing with the quotes
doesn't help either. I think that, in the python code I need to do some
extra call to some routine that do the evaluation/substitution... but I
don't know which.

Anyway, I uncluded a code thingy below, (basically the code  from
the How-to)

Can anyone help me on this ?

TIA,

Sloot.
