ComponentLikeModel seems quite out of sync Left over from the fabrik experiment. After a good code reading I think that we can remove this class. duplicate:from: -> no sender addPinFromSpec: PinMorph was removed previously so let us remove it. :) choosePartName is duplicated choosePartName is only invoked by some menus It seems that the internalName of the debugMenu of the debug halo is somehow change the instance variable name of the selected object. There is no implementors of copySlotMethodsFrom: so : delete init* methods are about pin nameMeIn: is only invoked from init* method I imagine that you are convinced that removing this class is good.
