There's your problem. You should also inherit from NSTableDataSource:

	class entityTable(NSObject, NSTableDataSource):
		...

This is necessary to make sure that the bridge knows the right method 
signatures for Objective-C: A number of the methods in the datasource 
protocol use plain C types as arguments or return value, without this 
hint the bridge assumes that all arguments and return values are 
objects.
