Hi!
The proposed solution does not work with Modal Windows!!
* http://osdir.com/ml/users-wicket.apache.org/2009-11/msg00076.html
Modal windws have a fake parent form:
<form style="border-width: 0px; margin: 0px; padding: 0px;
background-color: transparent; position: static;">
.. and ofcourse it does not have a hidden input field...
.. so the solution gets a bit nastier...
.. we must fake the hidden field value into the request ... ?
Is there another less pervasive way to do this? Maybe alter wicket a bit ;) ?
The solution here is implementation specific and probably works with jetty only:
public abstract class
AjaxFormSubmittingChangeListenerDropDownChoice<T> extends
DropDownChoice<T> {
private final static Method hiddenFieldGetter;
static {
try {
hiddenFieldGetter = Form.class.getDeclaredMethod("getHiddenFieldId");
hiddenFieldGetter.setAccessible(true);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
/** Initialize */ {
add(new AjaxFormSubmitBehavior(JavaScriptConstants.ONCHANGE) {
@Override
protected void onError(AjaxRequestTarget target) {
AjaxFormSubmittingChangeListenerDropDownChoice.this.onError(target);
}
@Override
protected void onSubmit(AjaxRequestTarget target) {
AjaxFormSubmittingChangeListenerDropDownChoice.this.onSubmit(target);
}
/**
* @see
org.apache.wicket.ajax.form.AjaxFormSubmitBehavior#onEvent(org.apache.wicket.ajax.AjaxRequestTarget)
*/
@Override
protected void onEvent(AjaxRequestTarget target) {
org.mortbay.util.MultiMap parameters =
((org.mortbay.jetty.Request) ((WebRequest)
getRequest()).getHttpServletRequest()).getParameters();
parameters.put(getHiddenFieldId(AjaxFormSubmittingChangeListenerDropDownChoice.this.getForm()),
AjaxFormSubmittingChangeListenerDropDownChoice.this.urlFor(IOnChangeListener.INTERFACE));
super.onEvent(target);
}
/**
* @param form
* @return String
*/
private String getHiddenFieldId(Form<?> form) {
try {
Form<?> root = form.getRootForm();
return (String) hiddenFieldGetter.invoke(root);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
});
}
}
