Re: Calling methods with variable arguments

Thanks, Dirk.  I believe that's exactly what I need if I'm going to  
figure out how to get this darn method working.

I'd advise you to use "objc.registerMetaDataForSelector" option unless  
you have a lot more metadata to specify. The bridgesupport files are a  
slightly enhanced version of the files generated by gen_bridge_metadata 
(1),  but sadly enough the PyObjC tools for creating and maintaining  
these files are more or less broken at the moment.
