hi there
here's a smaller, hopefully more clearer example of a problem I have
been stuck on. I should probably also lead off by saying that I
think what I am asking is basically this question.
http://www.mail-archive.com/zope3-users@zope.org/msg00052.html
However I have read objectwidget.txt( http://svn.zope.org/Zope3/trunk/
src/zope/app/form/browser/objectwidget.txt ) several times and I
don't see where a "custom widget" gets created. I also suspect that
because the "object" I need to create a custom widget for has more
than just one field I have to do something different.
If there's a short fix for the problem that would be great, otherwise
a little explanation to point me in the right direction would be
greatly appreciated too.
thanks.
