[Zope] Using string.split() on a DTML method

[Oscar Picasso]

Try this, I think it should work:
<dtml-with "_.namespace(var1=_.string.split(_['category_list_cookie'], ':'))">

Often replacing name_of_my_variable by _['name_of_my_variable'] produce
better results.

I even don't know why in this case and I gave up trying to find the reasons
until I can get a good documentation explaning how and why things work in
Zope.

An idea: there are about 1500 members in zope.org. If everyone gives $200
the total is $300 000. For that amount I think we could find a good team of
writers that could quickly write real good and complete documentation not
only targeted to top gun programmers in Zope.

What do you think about that? If DC could also give its opinion. For my
part I would give up to $400 just for that.

Open source doesn't mean poor documentation. Look at Python. I know that
everybody involved in Zope development does the best he can as I can see
when I receive answers to my questions.
