[jira] Commented: (WICKET-1826) Forms + ModalWindow + AjaxSubmitLink + FormComponent#isInputNullable

["Vladimir Kovalyuk (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-1826?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12703580#action_12703580 ] 

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.

> 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.
