[Zope3-Users] Form for list of lists

[Cliff Ford]

Thanks (roger) for the tips. I was trying to use a single custom widget 
- taking that out gave the expected default behaviour. I needed a much 
more customised form, so after many false steps, and for the benefit of 
anyone else who needs to know this is what I did:

1. Put an 'update' method definition in the thingy content type 
Interface and Class Implementation.

2. Created a custom thingy Page Template for the edit form.

3. Used template="thingy_template.pt" and 
class="site.thingy.thingyClass" definitions in the editform 
configuration. (No custom widgets.)

Seems very simple! I guess the problem for the Zope 3 newcomer is 
knowing which bits if the framework to use and which to replace.
