Vladimir Kovalyuk commented on WICKET-1826:
-------------------------------------------
Thanks Martin for the suggestion. The following workaround works:
Replace your form in ModalWindow with
public class ModalWindowForm<T> extends Form<T> {
public ModalWindowForm(String id) {
super(id);
}
@Override
public Form<?> getRootForm() {
Form<?> form = super.getRootForm();
if ((findParent(ModalWindow.class) != null) &&
(form.findParent(ModalWindow.class) == null))
return this;
else
return form;
}
}
What is not working is placing modal window form into another page form, even a
root form.
> Forms + ModalWindow + AjaxSubmitLink + FormComponent#isInputNullable

> URL: https://issues.apache.org/jira/browse/WICKET-1826
> Project: Wicket
> Issue Type: Bug
> Components: wicket, wicket-extensions
> Affects Versions: 1.3.3
> Reporter: German Morales
> Assignee: Matej Knopp
> Priority: Minor
> Attachments: modalwindowform.jar, modalwindowform.jar
>
>
> Submiting a form which is inside a ModalWindow, wicket javascript sends only
> the information for the modal window's form, but not for the root form of the
> page (because ModalWindow hangs its own div at body level).
> On Wicket server side, the form processing is done for the root form, which
> calls inputChanged for all the components in the page, but the javascript
> side didn't send the information for them, and then some of them go wrong.
> That happens to FormComponents which have isInputNullable in true.
> More description and proposed solutions in the (to be) attached quickstart
> project.
