Thanks Igor, my use case was an attempt to solve a bigger problem. Let me
try to describe the main problem I am trying to solve:
I have 1 big form with 3 distinct sections. Each section has an "update"
link which should run every FormComponent's validators for that section. The
trick is I can't use form submission because I don't want to validate the
other parts of the form, just that 1 section and provide error feedback if
necessary. The final button on the form is an actual submit, which will run
through every FormComponent's validators on the page. I thought about
splitting it up into 3 separate forms so each "update" link is actually a
submit, but the final button needs to validate every input in every section
- so that's why I'm using 1 form. I thought about nested forms as well, but
that isn't syntactically correct in HTML.
The crux of the problem is I need to run validators for only specific
FormComponents without doing a form submit. Is there any way I can do that
with wicket?
Thanks,
Tony
