[Grok-dev] subclassing grok.Container

[Christian Klinger]

Hi Grok Developers,

i try to make a Container Implementation for strom.zope [1].
I take many ideas from the z3c.zalchemy package in
zope.svn [2].

I think i have some problems by subclassing my StormContainer with
grok.Container.

This is my implementation:

app.py
======
from megrok.storm.stormcontainer import StormContainer

class PersonContainer(StormContainer, grok.Container):
     def __init__(self):
         super(PersonContainer, self).__init__()
         self.setClassName('person.person.person.Person')

class Index(grok.View):
     grok.name('index')
     grok.context(PersonContainer)


class CreatePerson(grok.AddForm):
     grok.context(PersonContainer)
     form_fields = grok.AutoFields(IPerson)

     @grok.action('Create')
     def create(self, **kw):


The Index work on the PersonContainer.

If i try to access <instance of PersonContainer>/createperson
i got the error at the end of this mail.

If i change the order of my BaseClases for
PersonConatiner in: PersonContainer(grok.Container, StromContainer)
i get the createperson AddForm. But i don´t get the StormContainer
Methods.

Any hints?

Christian
