Hi,

I'm using ATL plugin, however my transformation class has 2 metamodels as "IN" that will generate a model that uses just one metamodel as "OUT".

But, I'm getting the following error:


Exception in thread "main" java.lang.NullPointerException
at org.eclipse.m2m.atl.core.emf.EMFInjector.inject(EMFInjector.java:58)
at org.eclipse.m2m.atl.core.emf.EMFInjector.inject(EMFInjector.java:84)
at org.eclipse.m2m.atl.class2.files.Class2.loadModels(Class2.java:124)
at org.eclipse.m2m.atl.class2.files.Class2.main(Class2.java:80)



What I need to do to fix it?
