I'm trying to understand how it could be that after reading global context into a flow context, checking for the existence of a value ("on") in the flow context in order to determine what groups I need to serve, that action in itself changes the global context. I've asked a friend and we are getting no where.
Try the code I hope it is exemplary as a debugging routine.....I can't see where it would go as it does.....
This will allow you to build the global, array and fish for data...
