Tarcísio,

That's at this line of code:

initializationDependencies.add(findGenClassifier(eClassifier).getGenPackage());

That implies there either eClassifier is null, or there is no GenPackage
available for it. Try using Reload... on the *.genmodel to ensure that
all the other *.genmodel it depends on are available.
