[Moose-dev] FAMIXType>>incomingAccesses

#flatCollect:. In my case, the variable 'attributes' is of type http://damiencassou.seasidehosting.st FAMIXType>>incomingAccesses ^ self privateState cacheAt: #incomingAccesses ifAbsentPut: [ attributes flatCollect: [ :each | each incomingAccesses ] ] Hi, in this method when the cache is empty, it is initialized with the result of FMMultivalueLink. When sending #flatCollect: to a FMMultiValueLink, the result is an OrderedCollection (because FMMultiValueLink>>#species returns OrderedCollection). This means that it is no more possible to update the list of incomingAccesses. Is that the desired behavior? In my case, this behavior triggers a bug. When the following method is FMMultiValueLink class>>on: element update: selector from: old to: new "refresh the other side of the relations to reflect change in value" old ~= new ifTrue: [ old notNil ifTrue: [ (old perform: selector) unsafeRemove: element ]. new notNil ifTrue: [ (new perform: selector) unsafeAdd: element ]]. ^ new executed while importing a mse, I get a DNU: This is because the (new perform: selector) expression returns an OrderedCollection that does not understand #unsafeAdd: (selector equals to #incomingAccesses).
