RE: custom edit page not possible

[Ken in Nashua]

here is the actual error

An unexpected application exception has occurred.java.lang.RuntimeExceptionPage
 edit/Coach did not generate any markup when rendered. This could be 
because its template file could not be located, or because a render 
phase method in the page prevented rendering.


java/org.tynamo.examples.hibernatesecurity.pages.edit.CoachEdit.java



resources/org.tynamo.examples.hibernatesecurity.pages.edit.CoachEdit.tml

webapp/edit/CoachEdit.tml

I tried locating the template in the two above places but it still does find it.
according to tapestry docs, it is valid to locate pages beneath the pages dir 
and other folders beneath

could a render phase method be tripping it up ?
