How to Solve MWE/Xpand Workflow Problems/Errors

What to Check :

1. Check your model file (.xmi). See: http://spring-java-ee.blogspot.com/2010/12/fixing-eclipse-mwe-error-workflow.html

2. Check your plugin.xml file, make sure it contains extension on org.eclipse.emf.ecore.generated_package . Sample:

   <extension point="org.eclipse.emf.ecore.generated_package">
      <package
            uri="http://www.bippo.co.id/shop/3.0/magentoconfig/1.0"
            class="id.co.bippo.magento.config.MagentoConfigPackage"/>
   </extension>

3. Check that you've (re-)generated your model classes. Open your .genmodel and regenerate the Model.
