It trickie since it seems that Tapestry could call toString() on anything
without requiring this registration step. In this simplistic case,
registration didn't really tell it anything. But - given this registration
step - a few things make sense like ... before doing this, listing the
column name in the reorder clause of a t:grid was throwing an exception.

This exception happened because BeanModelSource didn't create a in a BeanModel property for Topic's classification property because it didn't know the Tapestry type for the Classification class. It's a very different issue.

:) One day - I hope to contribute BACK to Tapestry and than ... will have
arrived.

Everybody needs help and everybody can help. :)
I didn't know that just providing a Tapestry type for a class would make BeanModelSource handle it. I learned something today. :)

Thanks for your timely input. One last post on the way.

You're welcome! :)
