Hello,
I am doing a M2M transformation with eclipse modeling tools, using oaw. I am on a WindowsXP machine and have full admin permissions. The transformation part is going fine but when the Writer tries to write the generated target model to the xmi file I am getting a null point exception (at least that is what I think is going on).
This is the output of the console:
INFO: Reader(xmiHilesParser): Loading model from platform:/resource/MyProject.generator/models/System.xmi
12/10/2009 12:12:42 PM org.eclipse.emf.mwe.core.container.CompositeComponent internalInvoke
INFO: XtendComponent: executing 'transformations::M2M'

12/10/2009 12:12:43 PM org.eclipse.emf.mwe.core.WorkflowRunner executeWorkflow
GRAVE: null
java.lang.NullPointerException
Even with this error the Buzzer.xmi file is generated but nothing gets written to it.
Any ideas?

It happened to be an attribute in the target model that didn't have the EType attribute set. The wierd thing is that it validated ok.
Any ideas on what to configure on the validator options to make it check for EType attribute set?
