AjaxFormComponentUpdatingBehavior must be used on a FormComponent (sub)class.

I'm not sure what Igor meant with this suggestion.

I think .setDefaultButton() should do what you need.

Here is another suggestion from me:

Add a non-Ajax behavior to the text field which adds 'keyup' event
handler. When the user types something in the field then check the
keyCode from the event and if it is 13 then call
'document.getElementById(submitButtonId).click()'.

I describe my problem agin

I have a form and few panels in it.

In panel 'A' i have search button , panle 'A' consist of set of other panels 
'B'.
panel 'B' has few fields for example field 'F' 

Each panel is implemented in sepearate java class

I have requirement wherein after entering text in the field 'F' on press of 
Enter 
button search should be performed with out click of search button.

To achieve this i tried following snippet

 add(new AjaxEventBehavior(onkeypress)
  {
@Override protected CharSequence getCallbackScript(boolean 
onlyTargetActivePage)
{
  return generateCallbackScript(wicketAjaxGet(' + 
getCallbackUrl(onlyTargetActivePage) +  + KEYPRESS_PARAM + 
='+wicketKeyCode(event));
}

@Override protected void onEvent(AjaxRequestTarget target)
{
  String paramValue = 
RequestCycle.get().getRequest().getParameter(KEYPRESS_PARAM);
  int key = Integer.parseInt(paramValue);
if (key == 13)
{
   submitSearchForm();
 }
}

});
but using above the text in the field is cleared and get wrong search. but when 
i remove focus from the field and press Enter i get desired result.

My question here is how to perform search, remaining in the field(with focus in 
the field)

or their any other approach to get my requirement 

i also tried
 Form form = findParent(Form.class);
if (form != null)
{
  form.setDefaultButton(searchButton);
}

but form is always null for me

i also tried Igor's idea

i get below error on using AjaxFormComponentUpdatingBehavior
