I think I have it figured out.
The form was basically OK - except that on the FIRST render, the 'anyMatching'
was null, therefore false - so only a single component was being rendered and
recorded, via the <input type="hidden" name="Form0" value="1"/>
On the rewind, the 'currently selected' category was being set, which meant
that the second render DID include a second component. Because the count was
out, I think Form.renderComponent() was throwing a StaleLink exception.
Is there any way to propagate th exception dump to the stale link page? It
would have helped me discovering this problem immensely (I would have known
immediately what was kind of wrong, rather than having to make educated
guesses).
For my peace of mind, does my own diagnosis of the problem sound about right?
