Commented Issue: LongListSelector SelectionChanged doesn't get fired [9359]

In the Aug. release the SelectionChanged doesn't get fired anymore (at least in my application that was using it with the older release)

I had the same Issue with the Nov. release (I skipped the Aug. release) with my WP7 Application, which was published with the Feb. Release: SelectionChanged is not fired anymore.
In my case, it was because I had Buttons in the ItemsTemplate and GroupHeaderTemplate. I changed them to Grid, and the event gets fired again...
I found by debugging that the ListBox which is used by the implementation of the LongListSelector is not fireing the event if the items are buttons.
Did no further investiagtions since in mz case I could easilz change them to Grid elements...
