                 Key: FORGE-418
                 URL: https://issues.jboss.org/browse/FORGE-418

          Issue Type: Bug
          Components: Scaffold
    Affects Versions: 1.0.0.Beta5
            Reporter: Paul Bakker


On a project where I just created the first scaffold pages the following command gives a null pointer. I fixed this issue and a pull request will follow.
