"onsubmit" probably doesn't exist for <select>. Have you
looked at the ajax debug console (available when running
Wicket in development mode, e.g.
-Dwicket.configuration=DEVELOPMENT )?

That sounds strange, by the way.

You're just updating categoriaPai with the values from the
server, whenever its selection is changed, without ever
submitting them to the server.
AjaxFormComponentUpdatingBehavior does not submit the whole
form -- for that you need to use some *submitting*behavior.
Look at the source code of the different Ajax*Form*Behavior
to see better what they do.
