[Zope] get property of type 'list'

[Jim Washington]

Hi, Andrei

I think I have it figured out.  I just submitted something similar to
the Collector about an analogous problem I have been having with 'lines'
properties.

When you create your tokens property, you should make its value a
string, like:

'1 2 3'

not a list: [1, 2, 3]

If your data is in a list and you want to use that list as tokens, you
need to join the list into a string first:

mylist = ['1', '2', '3']
fortokens = string.join(mylist,' ')

That's the python, but you can do it in DTML using _.string.join(.  Be
careful to convert your integers to strings first.

What's happening to you is that the string representation of the list,
"[1, 2, 3]" is getting stored verbatim as your tokens property, and
ZPublisher/Converters.py is then splitting it on the spaces when you ask
for it. Which is how you get that weird '[1,' '2,' '3]'.
