Wicket passes the submitting component as argument to this method. ^^


 // this returns null
 IFormSubmitter btn = this.findSubmittingButton();

 if (btn == ...) {
 // do something before validation
 }

 super.process(submittingComponent);
 }


 The only way I could make this work so far is something like this:

 public void process(IFormSubmitter submittingComponent) {
 IFormSubmitter btn = this.findSubmittingButton();
 String qs = this.getRequest().getUrl().getQueryString();

 if (qs.contains(myButtonName)) {


Can you show us all GET and POST parameters ?


 // do something
 }

 super.process(submittingComponent);
  }

 This is ugly.  Hoping there is a better way.

Re: Determine which submit buttons was pressed

Maybe I'm missing something but it seems to me that the submittingComponent
parameter passed to process is just an anonymously generated class that
implements IFormSubmitter.  Although it is not null when process is called,
it only gives me access to the form and whether or not default form
processing is enabled.  Is there someway that this can lead me to the button
that triggered the submit?

 I have a form with two AjaxButtons.  I need to know which button was
 pressed
 before form validation takes place.  By the time the onSubmit or onError
 methods on AjaxButton are called, its to late for what I need.  Is there
 anything that can be done to identify the button prior to the process
 method
 of the form being called?  I suppose a hidden input identifying the button
 could be added to the form and altered using Javascript prior to the
 request.
