When I am developing an application, I'm normally only interested in valid submits or error submits. Not the 'advanced submit' which occurs before validation.

I find the name 'xxxValidSubmit' kind of not what I'm looking for. Having onError and onSubmit should suffice. The pre-validation submit shuold fall in the advanced section, and be targeted as such.

Having an onError which will be called when (one of) the validators fail, should push most users into using the validators and onError, instead of parsing the submitted values directly in the onPreValidationSubmit().

so, maybe:

onSubmit() - IFormSubmitListener method
onValidSubmit() - Form method called when valid form is submitted
onError() - Form method called when validation errors occur

?

of course this makes me want to rename the event handlers in ILinkListener, IOnChangeListener, IRedirectListener and IResourceListener...
i'm good with the onX() pattern for events. should we make this more consistent like this?

we could call it onValidSubmit() if you like, but onSubmit() is asking for trouble because it's not formSubmitted(), which is the onSubmit() handler (handles form submits, but not validated form submits). if you want to handle all form submissions, it's formSubmitted(). we could change that one to onSubmit() except that none of the other IResourceRequestListener subclasses use this pattern...

I don't know... I like onSubmit etc (short and to the point, consistent with e.g. onLinkClicked). On the other hand, onLinkClicked will be called directly/ is the same as the interface method, but from handleXXX it is clear (at least to me) that Wicket did some processing after the interface method was called.

If anything, the rename should have been to:
- onSubmit()
and create a new one if you want to differentiate an error condition:
- onError()

This is more consistent with the rest of Wicket: event handlers begin always with 'on'.

Hi,

I was checkout out HEAD and encountered numerous compilation problems due to this rename. Why was this done?
