[Zope] Inheritance (?) problem

Hi,
I have a pure-python (no Zope classes around) 'form' class like this:
class form:
def __init__(self, id):
self.id = id
def actionTarget(self, REQUEST={}):
"Main entry point."
return 'foo'
>From this class I derive a subclass
class zopeForm (SimpleItem.SimpleItem, form):
def actionTarget(self, REQUEST={}):
"Main entry point."
# ... other thing done here...
form.actionTarget (self, REQUEST)
The zopeForm class is part of a product so I have instances of
zopeForm (say 'zf') in a folder (say 'foo'). Now I would like to visit
the URL
...../foo/zf/actionTarget
but I get the following error:
Error Type: TypeError
Error Value: unbound method must be called with
class instance 1st argument
but 'self' in the call to form.actionTarget should be a zopeForm
instance!
If I change zopeForm.actionTarget to:
def actionTarget(self, REQUEST={}):
"Main entry point. Passing http REQUEST"
raise self
I get
Error Type: TypeError
Error Value: exceptions must be strings, classes, or instances
and if I change it to:
def actionTarget(self, REQUEST={}):
"Main entry point. Passing http REQUEST"
raise str(self)
I get
Error Type:
Error Value: None
It seems I'm missing something....
Any hint?
TIA, Luca
