[Moose-dev] MooseGroups'concatenation - side effect

Hello, I got some problems by concatenating some mooseGroups together. You can evaluate this script in a workspace (it correspond to what I did in my code): |mooseModel| Transcript open. MooseScripts createLightModelForLAN. mooseModel := MooseModel root allModels detect: [:aMooseModel | aMooseModel name ='lightLAN']. "at the begening, all famixClasses from this model have methods" Transcript show: (mooseModel allModelClasses select: [:each | each methods isEmpty]) size asString, String cr. "here we do several concatenations with methods from all FAMIXClasses:" mooseModel allModelClasses do: [:aFamixClass | aFamixClass methods , aFamixClass inheritedMethods ]. "let see the new result: " Transcript show: (mooseModel allModelClasses select: [:each | each methods isEmpty]) size asString, String cr. You can see that after the concatenations, some FAMIXClasses have lost their methods. Is it a real problem or is it me that is missing something obvious?
