I always thought it would be nice if tap could generate a drop down
given just a list - it could take the object id and toString() as values

There are two problems that you need to solve when writing a <select>:
* How do you map objects to option values? If you're using
tapestry-hibernate, this is already done. If not, Tapestry just cannot
know how to do that. Anyway, writing your own ValueEncoder is easy.
* What objects will be used as options? There's no way for Tapestry to do
that automatically in a reasonable way even when using tapestry-hibernate.
And SelectModelFactory already does the heavy lifting for you.
