OrderedMultiSelectWidget in Zope2: context weirdness?
|
|
I'm looking at the code for OrderedMultiSelectWidget, in
zope.app.form.browser.itemswidgets (line 535).
This code doesn't make sense to me:
if hasattr(self.context.context, self.context.__name__):
available_values = self.context.get(self.context.context)
else:
available_values = []
From what I can tell, this code is grabbing anything on the current
content/view that's named the same as the name of the vocabulary
provider. This bit me earlier with this error:

TypeError: iterable argument required
I had a named utility that was mapped to a function called 'activities'
which provides IVocabularyFactory. I had a browser form page that had a
field in it that used that named utility. The form class had a method on
it called 'activities'. Through some pdb digging, I was able to figure
out that it was grabbing the view method and not the function. It makes
sense looking at the code, but why would it work that way? Am I looking
at this wrong, or is this a bug?
My setup :
Plone 3.0.6 (according to Plone control pannel.. it's supposed to be 3.1.1)
CMF 2.1.1
Zope (Zope 2.10.5-final, python 2.4.3, linux2)
Python 2.4.3 (#2, Mar 7 2008, 01:58:20) [GCC 4.0.3 (Ubuntu 4.0.3-1ubuntu5)]
PIL 1.1.5
Five 1.5.6
I can put together some example code to reproduce the issue, if necessary.
Thanks,
JJ
