> Key: WICKET-6006
> URL: https://issues.apache.org/jira/browse/WICKET-6006
> Project: Wicket
> Issue Type: Bug
> Components: wicket-extensions
> Affects Versions: 6.20.0, 7.0.0
> Reporter: Martijn Dashorst
> Priority: Minor
> Attachments: WICKET-5948.7z
>
>
> When you have a panel inside a modal window, and the panel contains a form
> with e.g. a textarea, and you fill the textarea with about 10k of text, when
> the modal window is closed using closeCurrent() you get a 414 status error
> stating that the URL is too long (depends on the backend server).
> {code}
> public ModalPanel1(String id)
> {
> super(id);
> Form<?> form = new Form<>("form");
> add(form);
> add(new AjaxLink<Void>("closeCancel") {
> @Override
> public void onClick(AjaxRequestTarget target) {
> ModalWindow.closeCurrent(target);
> }
> });
> StringBuilder sb = new StringBuilder();
> for (int i = 0; i < 10000; i++)
> sb.append("a");
> form.add(new TextArea<>("bigFingTextField",
> Model.of(sb.toString())));
> }
> {code}
> Closing the window using ModalWindow.closeCurrent() will add the
> serializedForm of the modal window's contents (See line 656 of
> wicket-ajax-debug.js) to the URL that's sent to wicket. If the form inside
> the panel contains lots of data, this will exceed the maximum URL length...
> https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/ajax/res/js/wicket-ajax-jquery.js#L656
> The workaround is of course to use
> ModalWindow#close(IPartialPageRequestHandler) instead, however, why is
> ModalWindow#closeCurrent() even there, and why doesn't it properly close the
> window with the same behavior as the instance method?
