[Grok-dev] Adapter lookup problem

[Sebastian Ware]

I am stuck with an adapter lookup problem. I have an adapter for the  
context of my base class...

   module.py:

   class IAdaptIt(Interfaces):
       ...

   class MyBase(Object):
       ...

   class MyBaseAdapter(grok.Adapter):
      grok.context(MyBase)
      grok.provides(IAdaptIt)

      ...

And then I want to override it for an subclass...

   special.py

   class MySpecialised(module.MyBase):
      ...

   class MyExtendedAdapter(grok.Adapter):
       grok.context(MySpecialised)
       grok.provides(module.IAdaptIt)

       ...

But when I try to adapt an object of type [MySpecialised] I keep on  
getting [MyBaseAdapter] instead of [MyExtendedAdapter]. Something like  
this...

    >>> obj = special.MySpecialised()
    >>> adapter = module.IAdaptIt(obj)
    >>> adapter
    [module.MyBaseAdapter]

But I want adapter to return [MyExtendedAdapter].

Is there anything obviously wrong? How do I debug adapter lookup order?
