SV: Override fragments in subclasses
So in my parent html : body span wicket:id=myDiv/span div wicket:id=myNewPanel/div div wicket:id=myNewPanel2/div /body And add a label with id myDiv in related parent java. This part is common to all classes. But when I render the TestFormOne, that doesn't work because, apparently the label myDiv must be define in subclass. You should add a default component for it in the parent class then use replace() in subclasses as needed. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: SV: Override fragments in subclasses
That's what I did when the component has to be overriden in subclasses.
But how does it work when the component is common to every concrete page? I
would not want to redefine common component in every concrete page.
Let's see my example, In my parent page :
public abstract class TestForm extends WebPage {
public TestForm() {
add(new Label(myDiv, my div from test form)); = common to every
concrete page
add(createDivWithComponent(myNewPanel)); = has to be redefine by
each concrete page
add(createDivWithComponent2(myNewPanel2)); = has to be redefine
by each concrete page
}
protected abstract WebMarkupContainer createDivWithComponent(String
divId);
protected abstract WebMarkupContainer createDivWithComponent2(String
divId);
}
body
div wicket:id=myNewPanel/div
div wicket:id=myNewPanel2/div
/body
And, the concrete page :
public class TestFormOne extends TestForm {
public TestFormOne() {
super();
}
@Override
protected WebMarkupContainer createDivWithComponent(String divId) {
WebMarkupContainer container = new WebMarkupContainer(divId);
container.add(new Label(label,My very good label 1));
return container;
}
@Override
protected WebMarkupContainer createDivWithComponent2(String divId) {
WebMarkupContainer container = new WebMarkupContainer(divId);
WebMarkupContainer container2 = new WebMarkupContainer(div1);
container2.add(new Label(label2,My very good label 2));
container.add(container2);
return container;
}
}
body
div wicket:id=myNewPanel/div
div wicket:id=myNewPanel2/div
/body
And this is the error message I get : WicketMessage: The component(s) below
failed to render. A common problem is that you have added a component in
code but forgot to reference it in the markup (thus the component will never
be rendered).1. [Component id = myDiv]
What did I miss?
Thank you.

Re: SV: Override fragments in subclasses
Ok,
There was a problem when copy/paste html, sorry about that:
TestForm.html (parent html):
body
div wicket:id=myNewPanel/div
div wicket:id=myNewPanel2/div
/body
and TestFormOne.html(subclass html):
body
wicket:fragment wicket:id=myNewPanel
/wicket:fragment
wicket:fragment wicket:id=myNewPanel2
div wicket:id=div1/div
/wicket:fragment
/body

Re: SV: Override fragments in subclasses
Hi,
I think you should provide component classes that are responsible for sub
elements
class TestFormPanel extends Panel {
public TestFormPanel(String markupId) {
super(markupId);
add(new Label(label,My very good label 1));
}
}
TestFormPanel.html:
body
div wicket:id=label[label]/div
/body
and use it in TestFormOne
public class TestFormOne extends TestForm {
@Override
protected Component createDivWithComponent(String divId) {
return new TestFormPanel(divId);
}
But maybe I don't quite understand your problem.
Best Regards,
Ilja

An alternative is to have these either provide default/null components or throw

That markup is missing the div1 and label2 markup, but it does not get that
far because
