Thanks Grzegorz! Actually I was thinking about using Unions. In my case 
however this would make things more complicated. One of several reasons 
being that the selection list for my A widget gets filled dynamically. 
Now the set of possible values for my A widget is pretty much unlimited. 
That way I cannot setup union cases in my model as I do not know all 
possible values up-front.

Anyone knows if removing a selection list from a widget is possible or 
maybe if it's intentional that there's no such possibility?
