[Zope3-Users] One single EditForm for several objects

Hi there,


I have a Problem regarding to the creation and the editing of several
objects with one single form.

I do the creation with an AddForm, which uses formlib, the schemas
IFooContainer und IFooContained and a modified createAndAdd function.
Once the form is sent correctly, it creates a FooContainer object, a
FooContained object and adds FooContained to FooContainer. That's the
way it should be and that's the way it already works.

The actual problem is the EditForm. Basically I do the same as above,
using formlib and the two schemas. But now I get the following


2006-11-03T10:51:55 ERROR SiteError

Traceback (most recent call last):

  File "C:\Python24\Lib\site-packages\zope\publisher\publish.py", line

682, in __call__

    raise TypeError("Could not adapt", obj, self)

TypeError: ('Could not adapt', <FooContainer object at 0x03080E30>,
<InterfaceClass IFooContained>)


The error seems to occur in the following line (the second one):

class MonolithicEditForm(form.EditForm):

  form_fields =

That works with the AddForm, but not with the EditForm. How can I tell
the system that several of the formfields belong to the FooContainer
object and the rest belongs to the FooContained object? Is there a way
to do this?


Thanks I advance,




PS: I'm working with Zope 3.3 and Python 2.4
