[Zope3-Users] EditForm fails in SiteManager because of containment constraint

[Christophe Combelles]

OK, I've finally found,
Actually, it was failing also in the content side

My object is not IContained.
And since I'm adding containment constraints, I guess my object was considered 
Contained (containment proxy?). So the EditForm was expecting __name__ and 
__parent__ and was failing somewhere.

I've just added omit('__name__', '__parent__') in the form and it works.

But I can't explain why I have to add this omit() when my object is not 
contained. Is it silly to add a containment constraint on a not Contained 
object?  Shouldn't the containment proxy manage this by itself?
