how to invoke javascript method after form validation?

[novotny <no...@gridsphere.org>]

Hi,

I have markup like <li class="noerror">Enter text<input type="text"
wicket:id="sometext"/>....

And I'm using FeedbackPanel currently, but instead of showing all the errors
at the top, we want to change class="noerror" to class="error" which seems
easier to do in javascript. But how can I indicate to wicket to invoke this
javascript function which changes class="noerror" to class="error" for those
fields that have errrors?
I'm open to other ideas, but I have lots of wicket panels and don't want to
have to add a lot more wicket code to every class e.g. doing <li
wicket:id=...> in markup and adding RepeatingView/Label solutions seems like
more work.

Thanks, Jason

Here's the easiest way that I can think of....

Create a behavior (extend AbstractBehavior) that assigns a class to the form
component of either "error" or "noerror" based on the component status.

Then, if you don't want to manually add it to every form component, I think
you could add a visitor to the form that adds the behavior to all form
components for you.

This is (IMHO) a better solution than JS - it works on the server side.
