[Moose-dev] connecting a smalltalk class and a FamixClass

hello all, I am trying to create a distribution map for a moose model representing Citezen. Now, for each class, I am trying to color it according to its authors information. The following script should work for me: |model packages| model := (MooseModel root allModels) first. packages := model allPackages. (DistributionMap onContainers: packages elements: (model allModelClasses) properties: [:cl | cl authors > 10] ) render open. However, the method "authors" that I am invoking on cl (a FamixClass) is not defined by FamixClass but it is described by ClassDescription. Is there anyway to connect a FamixClass to its corresponding Smalltalk class? I am thinking of getting the name of the FamixClass and somehow ask pharo to give me its corresponding Smalltalk class? Any ideas if that should work? thanx in advance, Usman
