Funnily enough I cannot recompile the class, the trait comes back :(

It is working .. in the image but I release the code I got a DNU

        MorphTreeModel setTraitComposition: {}.

telling to me that Array does not understand assertValidUser:



setTraitComposition: aTraitComposition
        | oldComposition |
        (self hasTraitComposition not and: [aTraitComposition isEmpty]) ifTrue:  
[^self].
        aTraitComposition assertValidUser: self.

        oldComposition := self traitComposition.
        self traitComposition: aTraitComposition.
        self applyChangesOfNewTraitCompositionReplacing: oldComposition.
       
        oldComposition traits do: [:each | each removeUser: self].
        aTraitComposition traits do: [:each | each addUser: self]
