> I've been trying to come up with a patch but work has been getting crazy and 
> I have been ill for days now.
> A detailed description of the problem (and apossible solution) is to be found 
> here:
> http://wiki.apache.org/jakarta-tapestry/GeoffLongmanSandbox
> In a nutshell, if a user references a Tapestry page whose class must be found 
> from a given list of packages it may be the case that way they have 
> referenced (by name) may mislead the ComponentClassProvider to look in the 
> wrong package. If that happens, the class is not found and (in most cases) 
> BasePage is assigned as the page class. Often this will break the application 
> if the page depends on a class other than BasePage. Depending on how the app 
> is set up there could be 3 or more legal ways to reference a page by name 
> (path parts) but only one way will result in the right page class being 
> located.
