Hi,

I had a look on that.

The problem is that in the method #primCollectAtScope, when the #collectAsSet finds a classScope = nil (for example, in a GlobaVariable) it inserts a SetElement and not nil.

primCollectAtScope: aScopeSymbol
    "
    ^ self opposites collectAtScope: aScopeSymbol
    "

    ^self storage collectAsSet: [ :dep | (self opposite: dep) perform: aScopeSymbol ].

See the difference:
#(nil) collectAsSet: #yourself.
#(nil) collect: #yourself.

So, if you check the method #collectAtScope: there is a filter for nil elements, but we will never have nil (just SetElement).

One trivial solution is:
primCollectAtScope: aScopeSymbol
    "
    ^ self opposites collectAtScope: aScopeSymbol
    "

    ^ (self storage collect: [ :dep | (self opposite: dep) perform: aScopeSymbol ]) asSet

I just commited it and the tests are green for FamixPropertiesTest.testHasTheSamePropertiesAs

ps: also updated the invocation from #queryAllOutgoingDependencies to #queryAllOutgoingAssociations Doru cited last email.

Hi Nicolas,

Thanks a lot.

I looked quickly into this. There is at least a simple problem: you are calling queryAllOutgoingDependencies, but this method does not exist anymore. I guess we should replace this with queryAllOutgoingAssociations.

Is this due to a wrongly published refactoring?

Cheers,
Doru
