Hi, I'm back with more annoying questions :)

Using #whenSelectedItemsChanged:, I see that the block is evaluated a lot of times:

log := OrderedCollection new.

roots := #(1 2) collect: [ :each |

TreeNodeModel new 

content: each;

selected: true;

yourself ].

TreeModel new

roots: roots;

multiSelection: true;

whenSelectedItemsChanged: [ :items |

log add: items ];

openWithSpec.

log ---> an OrderedCollection(#() an OrderedCollection(1) an OrderedCollection(1) an OrderedCollection(1 2) an OrderedCollection(1 2) an OrderedCollection(1 2))

I'd expect only one evaluation... is it a bug or a feature?

cheers,

Mart�n
