This is not really a bug. It's the expected behavior.

But maybe this has to be changed :)
(but I am on holidays now ^^)

Ben, why is this behavior expected? What purpose does this method serve if  
you can't get the new and old value? At least I think there should be a  
comment as I found it extremely confusing.

If you are interested in the items use whenSelectedItemChanged.
If you are interested in index, use whenSelectedIndexChanged.

If you do not care about the value, but just want to know when it changes,  
then you can use whenSelectionChanged:

I will add a comment

@marcus: I didn't tag it 2.0 because I was following your rules ;) I want  
everything in 2.0! But I'm trying to be realistic so we can get it out the  
door...
