Hi,
some widgets may require a valid context to work properly. one such
widget is z3c.formquery.
The attached patch passes the current widget's context to the sub
widgets during data conversion in z3c.form.converter.MultiConverter.
The patch handles this the same way as passing the form property is
implemented. (The patch is against current trunk).
Sorry, but I was not sure how to add a test for this. (However, there is
also no explicit test for passing the form property).
I ran the current test suite with python2.4 and it did not cause any
additional issues :) .
The second patch here was required on my system. It seems, that
zope.app.component is a missing dependency for z3c.form. (at least for
now).
cheers,
Gerhard
