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

[Christophe Combelles]

Hello,

I have a regular content object which uses the formlib for its edit view.
Nothing special, just like a Recipe.
But I want this object to only reside in the Site Manager, because it will be 
used as a configurable local utility (some kind of LocalKitchenTools utility)

Everything is perfect, and the EditForm works well until I want to tell this 
object to be only contained in the SiteManager. So I just add this statement in 
the interface:

containers(ILocalSiteManager)
or
containers(ISiteManagementFolder)

When I do any of these, the EditForm fails with a ComponentLookupError
What Am I missing? Why does a simple constraint create an error on this?

Christophe
