Re: Problem with IFormsubmitting
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:
.. 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 extends
DropDownChoice {
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);
}
}
});
}
}

Re: Problem with IFormsubmitting
Tnx. I would like to ask (myself?) whether it could be formulated
simply into a behavior that can be attached into any formcomponent.
Probably. I will work on this next.
Ofcourse if more people try the code in their applications we will
soon learn if it breaks something.

The power of this list is amazing - it seems you just had an entire thread

But seriously, did you have any remaining questions on this that we could

Hi!
One finishing touch is needed. The hidden field should be cleared

Re: Problem with IFormsubmitting
Hi!
Maybe this is the solution:
String url =
getRequest().getParameter(getHiddenFieldId());
if (!Strings.isEmpty(url))
{
dispatchEvent(getPage(), url);
}
??
Attach a change listener with ajax form submit?

Problem with IFormsubmitting
Hi!
I need to accomplish the following:
1. receive ajax onchange event from a formcomponent
2. receive "defaultformprocesing=false" style submit
3. repaint an area; I this is why I need the form to be really
submitted (=rawinput but not validated).
I have built a custom component FormSubmittingDropDownChoice.
The problem is that even if I press another submit component (button,
for example), the form allways assumes the formSubmitting component to
be FormSubmittingDropDownChoice. Why? Because the findSubmittingButton
is so simple that if FormSubmittingDropDownChoice has a value, it is
the submitting component.
Is there a workaround or fix? How could I achieve similar
functionality in a working manner? This works well if I click the
FormSubmittingDropDownChoice, otherwise it does not :(
package com.tustor.wicket.common.reusables.formcomponents;
public class FormSubmittingDropDownChoice extends DropDownChoice
implements IFormSubmittingComponent {
public FormSubmittingDropDownChoice(String id, various constructor options) {
super(id, choices, renderer);
