             Project: Tapestry 5
          Issue Type: Improvement
          Components: tapestry-core
    Affects Versions: 5.1.0.5

If a page has only constructores requiring parameters, then the following error message is shown.
It should tell the user as well, that a no-argument constructor is missing.
