Hi, I already spent 4 hours on this and am not anywhere near the solution :-( I think I got myself on a wrong track and cannot get out of it. So I will ask your help see if you can do better. From what I understood, the problem is not related to the metrics, but comes from accesses to global variables. When one does a atClassScope on a queryResult containing an access to a global variable, this one returns nil to the message claassScope (this is normal), and for some reason that I cannot understand the nil gets inserted in the storage of the queryResult in some cases (not always) in the form of a SetElement containing it. After lot of debugging, I finally got a method (LANInterface>>originate() ) that accesses (among other things) SmalltalkGlobalVariable. My problem is that from here the behaviour seems heratic to me :-( - 'theMethod queryOutgoingAccesses atClassScope' works,so it does filter out the nil coming from the 'SmalltalkGlobalVariable classScope' - 'theMethod queryOutgoingReferences atClassScope' also works (there is no global variable involved there anyway) - 'theMethod queryStaticOutgoingAssociations atClassScope', does not work, it contains a SetElement that contains a nil :-( What baffles me is that the definition of FAMIXMethod>>queryStaticOutgoingAssociations is:       ^ self queryOutgoingAccesses               addAll: self queryOutgoingReferences;               "addAll: self queryOutgoingInheritances;     -- inheritance does not make sense here"               yourself. I even simplified it a bit to be more sure: staticAssociations = all access + all inheritance. So taken together they exhibit the problem, but taking access alone access does not exhibit it. If I manually remove all references from the queryStaticOutgoingAssociations' result, then it works again, which is logical because this is the same as asking 'queryOutgoingAccesses' which already works Note: to remove elements from the resutls, I use an inspector on the MooseQueryResult: 'storage := storage reject: [:a|a class == FAMIXReference]' Even stranger to me, if I manually remove only one of the references (eg: 'storage := storage reject: [:a|a to name = 'String']'), then the result starts to be correct again. The test used to built the particular model I am wroking on is MooseModelOverviewPyramidExtensionsTest>>testoverviewPyramidMetrics So here I am. Maybe you can provide some fresh view on it?
