hi, I'm having problems with passing a number of parameters to a python script called by XML-RPC. I want some of the parameters to be optional, and passed as empty strings. I have tried to do this by setting default values as empty quoted strings. But playing around even with setting non-empty default values in a list of params doesn't seem to work. e.g. if I set the parameter list of the method as: a, b="aardvark" and then test the script, if I leave b empty, the default aardvark is assumed. but if I switch the order round, and set the param list as: b="aardvark", a and do the same, the script breaks with the error 'the parameter b was ommited from request. could anyone tell me how I do this: i.e. have a parameter list with some values set with defaults, not just the last one?
