Dear MOOSEers, As an exercise, I am parsing Java files and loading the corresponding Java classes in a moose model. Whereas it seems that I fill the model well, I got a rollback when using the Moose GUI façade. I spend some time on it, but I failed in trying to debug it. It seems that a famix element should know about the model it is part of. But I do not know how to set it. the error comes from the method: FAMIXAbstractStruture >>incomingAccesses ^self entityGroups at: #incomingAccesses ifAbsentPut: [self mooseModel allAccesses select: [:each | each accesses = self]]. self mooseModel returns nil If you want to try, you can load the package JavaSupport4Moose in the SCGStore. I attached a short java file to try this. Once the package loaded, click on the "..." button in the Moose GUI. The test Java4MOOSETest>>testReadingJavaFile is green cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
