[Grok-dev] About interfaces

[Santiago Videla]

I have somethig like this:
interfaces.py

class IPerson(Interface):
    """
    Personal data interface
    """
    fullname = schema.TextLine(title=u"Fullname",
                            description=u"Enter the person fullname",
                            required=True,
                            default=u'',
                            )
...

class IClient(Interface):
    """
    Client of the company
    """
    client_type = schema.Choice(title=u"Client type",
                    required=True,
                    description=u"Select the client type",
                    values=['Bank','Broker','Other'],)
...

client.py

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

Thie works fine.

But I'm trying to use this:
in interfaces.py
class IClient(IPerson)
   ...
in client.py
class Client(grok.Container):
    implements(IClient)

but when I try to edit a client instance i get this:

  File "/home/sancho/buildout-eggs/grok-0.10-py2.4.egg/grok/formlib.py",
line 18, in success
    return self.success_handler(self.form, **data)
  File "/home/sancho/revoluciones/proyectos/sac/Sac/src/sac/client.py", line
109, in save
    self.applyData(self,**data)
  File "/home/sancho/buildout-eggs/grok-0.10-py2.4.egg/grok/components.py",
line 424, in applyData
    self.adapters, update=True)
  File "/home/sancho/buildout-eggs/grok-0.10-py2.4.egg/grok/formlib.py",
line 139, in apply_data_event
    changes = apply_data(context, form_fields, data, adapters, update)
  File "/home/sancho/buildout-eggs/grok-0.10-py2.4.egg/grok/formlib.py",
line 118, in apply_data
    adapter = interface(context)
TypeError: ('Could not adapt', <sac.client.EditClient object at 0x99de3ac>,
<InterfaceClass sac.interfaces.IPerson>)

help please?
