I'm not sure how good approach bindings is in this case. It seems like a weird hack :S
Furthermore, it doesn't seem to make too much sense to bind the selected index to a single variable because, as you say, I have multiple rows and the popupmenu for each one.
Actually I can think of one weird way of making it work: Having an instance variable "int selectedIndex" with ONLY a setter method (NOT a getter method). That way change in one of the rows will not propagate to other rows. And I can then do my stuff in the setter method. But hmm, this is just too weird to be the best solution available out there, assuming it even works :S
