No, I'm throwing the correct exception. Below is a code snippet:

def getDataObjectByGUID(self, guid):
        """Return a reference to a data object given its unique
        global identifier(GUID)."""

        try:
            self._acquire()
            dataObjList = self.getDataObjs()
            # Loop over all the elements in a list,
            for dobj in dataObjList:
                if dobj.getGUID() == guid:
                    return dobj

            # If we get here we didn't find it.
            msg = '^^%s: data object with GUID=%s not found.'
            raise ExceptionM.DataException(msg[2:] %(self.getName(),
guid))
        finally:
            self._release()

Can you post the IDL and a python code snippet?
It sounds like you're throwing a CORBA.UserException directly, but afaik
a concrete exception type defined in the IDL (exception { and raises on
the method) has to be thrown.
