Clay, I am not able to use ajax in this particular case because I have file inputs on the page, otherwise you are right the solution would be much easier if I were able to use ajax.
javascript: form.submit() would be what I am looking for except I would like the wicket side to understand the form was submitted via javascript and execute an onSubmit that is specific to this type of submission (similar to how a button has its own onSubmit that is executed with that specific button is used to submit the form). It sounds like for now I will have to use a hidden link and trigger its onClick event.
