Exactly.

I think that this is an acceptable workaround for now, unless changing  
the order of events in the case of user selection is a trivial change,  
which it sounds like it isn't.

I don't have a strong use case. I was reacting to the inconsistency- 
with-a-reason, from the point of view of the event handler. If there  
is a reasonable fix, we should do it, otherwise, we'll have to live  
with it.

Ultimately, I do think we need to add proper context information to  
all events. It just seems reasonable that if you say that "something"  
got selected, there is a way within the event of determining what the  
something is, so that you don't have a strong constraint about where  
to place your event handler. But that is a question for another thread  
probably.
