Hello,
I'm not sure this is a problem, but here is the error I had:
FAMIXMethod >> numberOfMessageSends <property: #MSG longName: 'Number of message sends' description: 'The number of message from a method'> ^self lookUpPropertyNamed: #MSG computedAs: [self mooseModel isSmalltalk ifTrue: [| parser | parser := VisualWorksParseTreeMetricCalculator new. parser *processMethod:* self *usingImporter: *nil *inModel:* nil. parser numberOfMessageSends] ifFalse: [-1]]
Here, to compute this property, we ask the smalltalk compiled method (throught the method in bold). So, if I generate a model, then remove a method in pharo, then ask the corresponding FAMIXMethod for #numberOfMessageSends, it will raise an error because it does not find the compiled method anyMore. Maybe we should force the computation of this kind of property at the model computation ?
