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
WicketMessage: Behavior
nl.planon.hera.filters.quicksearch.PnWebAdvancedSearchPanel$3 can only be added
to an instance of a FormComponentRoot
cause:org.apache.wicket.WicketRuntimeException: Behavior

to an instance of a FormComponent
