As I said to Martin, I will investigate why, but it�s a bit tricky
Must be some issue in MorphTreeMorph I introduced recently

Hi,

I am experiencing problems with #whenSelectedItemsChanged: on a TreeModel.

In particular, the block (i.e., argument of #whenSelectedItemsChanged: gets randomly executed a couple of times (3/4) the second time that the selection happens. The first time is fine. It looks like the registration of the �event� or �announcement� is done multiple times.

Any hint?

Cheers,
