... how can I construct a dynamic path like: getattr(self, 'personManager').getData().addPerson( firstname='max', lastname='miller') This does not like a path for me...
Okay, lets see: * you already know "getattr". It resolves simple attributes given by an expression * you can handle keyword parameters (your "firstname", "lastname") via a dictionary and the "apply" method (see Python library documentation: built-in function "apply"). * the difficult part is "getData().addPerson". You need to parse this and use "getattr", and "function call" to resolve this. Inside an External Method, you could use "eval" (as an alternative). But be caseful! Big security risk. You should probably use some from of "safe_eval" (--> search the archive). Dieter
