I think I was having a problem because I was using
AjaxFormComponentUpdatingBehavior to update the listbox when the textfield
changed. I wanted to add the Enter capability to that and that is where I
got a little confused. What seems to work is overriding the
getCallbackScript of the original keyup event to wrap the normal callback
script with an if stmt to control the flow based upon the key pressed.
Below is what seems to work. Are there other (better) ways to do this?
AjaxEventBehavior autoUpdate = new
AjaxFormComponentUpdatingBehavior("onkeyup") {
protected CharSequence getCallbackScript(CharSequence partialCall,
CharSequence onSuccessScript, CharSequence onFailureScript) {
final StringBuffer script = new StringBuffer();
script.append("var kc=wicketKeyCode(event); if (kc!=13) {");
script.append(super.getCallbackScript(partialCall, onSuccessScript,
onFailureScript));
script.append("} else {document.all.");
script.append(submit.getId());
script.append(".click();}");
return script;
}
