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.
