  Most likely you created your class abstract when it didn't need to be.  
Tapestry doesn't create an enhanced subclass if there are no 
<property-specification> elements.  A concrete class is never created by 
Tapestry in this case and since abstract classes cannot be instantiated, this 
exception pops up.  You either need to create a <property-specification> 
element or make your class concrete by removing the abstract identifier.
