In my case it was lots of trial and error to see how the engine  
behaved when relayering controls in groups. I just created a test  
stack and started experimenting. I needed to figure it out so I could  
represent custom objects using nested groups and reorder records that  
were displayed in groups that were scrolled using a parent group.

The fact that a Rev group uses a range of layers (indexes) to  
determine which controls are contained within it is what makes things  
difficult. In Revolution you can't say "make this control the third  
control in group "A". You have to adjust the layer of the control as  
well as other controls already in the group. If groups were true  
nested objects that knew something about their immediate children  
things would be different.
