[Moose-dev] Re: Jenkins build became unstable: moose-latest-dev #710

Hi, I reproduced the problem. It was due to FAMIXPackage>>weightedMethodCount :). I am describing the situation, because it will probably be useful for others that want to extend Moose with properties. You added: FAMIXPackage>>weightedMethodCount <MSEProperty: #weightedMethodCount type: #Number> <MSEComment: 'The sum of the complexity in a package'> ... This means that this property is described. And it also means that the Fame import/export will deal with it as well. Now, the fuel tests simply export a model and then import it back. This property gets exported, but when Fame tries to import it it crashes because there is no setter. So, one solution is to add FAMIXPackage>>weightedMethodCount: However, in this case, we deal with a property that is derived from the information inside the model, so we do not want to save it in the first place. Thus, the proper solution is to mark it as derived: FAMIXPackage>>weightedMethodCount <MSEProperty: #weightedMethodCount type: #Number> <MSEComment: 'The sum of the complexity in a package'> <derived> ...
