I'm trying to do this:

from zope.container.constraints import containers, contains 

class IFooContainer(Interface):
    contains('test.app.IFoo')

class FooContainer(grok.Container):
    grok.implements(IFooContainer)
    
class Test(grok.Application, grok.Container):
    grok.local_utility(FooContainer, provides=IFooContainer, public=True,
name_in_container='foos')

class IFoo(Interface):
    containers('test.app.IFooContainer')
    bar = schema.TextLine(title=u'Title')
    
class Foo(grok.Model):
    grok.implements(IFoo)
    
class AddFoo(grok.AddForm):
    grok.context(IFooContainer)
    form_fields = grok.AutoFields(IFoo)
    grok.name('add')
    
    @grok.action('Add')
    def Add(self, **data):
        foo = Foo()
        self.applyData(foo, **data)
        self.context[foo.bar] = foo
        self.redirect(self.url(foo))

If you then go to http://localhost:8080/test/foos/add
you get this dump:

Am I doing something wrong?
