Parent page container required in child page?
Hi,
I have a ParentPage and many sub class child pages that extend it. I
decided to add a root container element to the parent page, but this
breaks all ChildPage.add() method calls in the child pages. A solution
is to pass the root container to every child, but that is a lot of
work. Is there a cleaner way to solve this problem without breaking
all the child pages?
// ParentPage.java
public class ParentPage extends WebPage {
// Shared with sub classes
protected MarkupContainer rootContainer;
public ParentPage() {
rootContainer = new WebMarkupContainer("rootContainer");
add(rootContainer);
rootContainer.add(new Label("parentLabel", "Parent component"));
}
}
// ParentPage.html
ParentPage
// ChildPage.java
public class ChildPage extends ParentPage {
public ChildPage() {
// This should preferably be add() instead of rootContainer.add()
// So that I don't have such dependency on the parentPage.
rootContainer.add(new Label("childComponent", "Child component"));
}
}
// ChildPage.html
Child page

Thanks Sven and Martin!
I've tested it, it works perfectly.

Stateless ModalDialog
Hi,
Is it possible to create a stateless ModalDialog?
I tried the following code, but it results in an error. The error
doesn't occur when removing the getStatelessHint() overrides, but that
would make it stateful. If it's not possible, would it be possible
with the deprecated ModalWindow?
HTML Code:
.modal-dialog { border-radius: 5px; }
.modal-dialog .modal-dialog-content { display: flex;
flex-direction: column; }
.modal-dialog-overlay.current-focus-trap .modal-dialog-content
{ resize: both; }
.modal-dialog .modal-dialog-form { margin: 0; padding: 0;
overflow: hidden; flex: 1; display: flex; flex-direction: column; }
.modal-dialog .modal-dialog-header { border-radius: 5px 5px
0px 0px; background: #ffb158; margin: 0; padding-top: 4px; text-align:
center; }
.modal-dialog .modal-dialog-body { flex: 1; overflow-y: auto;
padding: 20px; }
.modal-dialog .modal-dialog-footer { padding: 5px; }
Open modal
Modal Dialog
Close modal
Java Code:
package org.example.modaltest;
import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.ajax.markup.html.AjaxLink;
import org.apache.wicket.extensions.ajax.markup.html.modal.ModalDialog;
import org.apache.wicket.extensions.ajax.markup.html.modal.theme.DefaultTheme;
import org.apache.wicket.markup.html.GenericWebPage;
import org.apache.wicket.markup.html.panel.Fragment;
public class ModalPage extends GenericWebPage {
public ModalPage() {
ModalDialog window = new ModalDialog("window");
window.add(new DefaultTheme());
window.setMarkupId("window");
window.setOutputMarkupId(true);
add(window);
Fragment modalContentFragment = new
Fragment(ModalDialog.CONTENT_ID, "modalContentFragment", this);
window.setContent(modalContentFragment);
modalContentFragment.setOutputMarkupId(true);
AjaxLink closeModalLink = new AjaxLink("closeModalLink") {
@Override
public void onClick(AjaxRequestTarget target) {
target.add(window);
ModalDialog window1 = (ModalDialog) findPage().get("window");
window1.close(target);
}
@Override
protected boolean getStatelessHint() {
return true;
}
};
closeModalLink.setOutputMarkupId(true);
modalContentFragment.add(closeModalLink);
AjaxLink openModalLink = new AjaxLink("openModalLink") {
@Override
public void onClick(AjaxRequestTarget target) {
ModalDialog window1 = (ModalDialog) findPage().get("window");
window1.open(target);
}
@Override
protected boolean getStatelessHint() {
return true;
}
};
add(openModalLink);
}
}
