Wow. So the response is no longer JSON, but a function call. Add the appropriate headers (Thank you Gabriel) and Prototype will do it all automatically. I suppose, therefore, that the param COULD be the name of an instance of an object and a method? For example : o_TabControl.addTab WOW! That is excellent and really simple to implement. Thank you. Once again, you've covered my membership fee!
