Just because your webservice offers a parameter called "foo" doesn't 
mean your Python code has to use the same name "foo". Pick a different 
name.

Or change your webservice to use abc_xyz instead.

It is an accident that getattr(self.object, 'method-name') works. You 
cannot rely on it, it is not supported by the language, and although it 
works today it may not work in the future.
