An null pointer exception throwed from DefaultDeclarativeQualifiedNameProvider, when I try to "Run As"->"Eclipse Application". I am using Xtext 2.1.

0 [Worker-0] ERROR org.eclipse.xtext.builder.impl.XtextBuilder -
java.lang.NullPointerException
at org.eclipse.xtext.naming.DefaultDeclarativeQualifiedNameProvider.getFullyQualifiedName(DefaultDeclarativeQualifiedNameProvider.java:58)

What I did:
1. create an empty Xtext project
2. copied content of Dsl.xtext and DslGenerator.xtend to the workspace from old project
3. modified the 'GenerateDsl.mwe2" to remove the Xbase stuff.


Please advice, thanks a lot!

I tried the greeting syntax comes with default project creation, the getFullyQualifiedName will not throw. So it should be a problem in my model, I am checking.
