That's an unexpected limitation!
In exceptional cases, you can revert to simpler methods; for instance, using
a simple <input type="text"/> rather than a TextField component, and
handling that part of the submission inside your listener method much like a
traditional servlet.
As a stop-gap, you should give explicit jwcids to ALL of your components, as
use shorter names ... this will buy you a lot
(if you see the repetition in the generated element ids string at the
root of your problem). This
may be a time to use less intuitive names (i.e., use abbreviations!).
