Hey,

in client.py, I defined

class EditClient(grok.EditForm):
    grok.context(Client)
    grok.name('edit')
    form_fields = grok.AutoFields(Client)
    template = grok.PageTemplateFile('form.pt')
    form_title = u'Edit client'

    @grok.action("Save")
    def save(self, **data):
        self.applyData(self,**data)
        self.redirect(self.url(self.context))

And I also have

class AddClient(grok.AddForm):
    grok.context(ClientsContainer)

    form_fields = grok.AutoFields(Client)
    template = grok.PageTemplateFile('form.pt')
    form_title = u'Add client'

    @grok.action("Add client")
    def add(self, **data):
        client = Client()
        self.applyData(client, **data)
        name = INameChooser(self.context).chooseName('client', client)
        self.context[name] = client
        self.redirect(self.url(self.context))

the AddClient form works fine using

class IClient(IPerson)

class Client(grok.Container ):
    implements(IClient)

but when I go to edit, i get the error

thanks in advance
