Project: Tapestry
Issue Type: Bug
Components: tapestry-core
Affects Versions: 5.0.10

Some of my pages inherit from a common abstract base class but even if I move
this to <root package>.base, I receive the following application exception:
Caused by: java.lang.RuntimeException: java.lang.ClassNotFoundException: caught
an exception while obtaining a class file for <root package>.pages.MyPage

Caused by: java.lang.RuntimeException: Base class <root
package>.base.AbstractPage (super class of <root package>.pages.MyPage) is not
in a controlled package and is therefore not valid. You should try moving the
class to package <root package>.base.
