[omniORB] omniORBpy newbie: returning interface from remote call

[gabriele renzi]

Hi everyone, 

I just started experimenting with omniORBpy today,
everything seemed to be working fine but now I hit a
strange problem. My IDL file looks like this 

module PSD {
 interface Calc {
  string myop(in string name,in string other);
 };
 interface CalcFactory {
  Calc client_instance(in string cname);
 };
};
omniidl seems to compile the idl fine, and I can get
the CalcFactory correctly via
 obj= orb.string_to_object(ior)
 cf = obj.narrow(PSD.CalcFactory)
 
but then if I try to call 
calc = cf.client_instance('name')
I get a 
CORBA.BAD_PARAM(omniORB.BAD_PARAM_WrongPythonType, 
CORBA.COMPLETED_MAYBE) exception.

The code in CalcFactoryImpl, the subclass of the
abstract PSD__POA.CalcFactory is like this:
def client_instance(self,key):
 client=CalcImpl() # PSD__POA.Calc subclass
 return client

Someone has a clue on what I may be doing wrong? Sorry
if I'm posing a dummy question.
