Hello, I am learning Wicket by reading <<Wicket in Action>>. I am using Wicket
1.4.5 and Java 6.
On page 244, the sample code is as follows:
private int counter = 0;
public MyPage() {
super(new CompoundPropertyModel(this));
final Label counterLabel = new Label("counter");
add(counterLabel);
counterLabel.setOutputMarkupId(true);
add(new AjaxLink("counterLabelLink")
@Override
public void onClick(AjaxRequestTarget target) {
counter++;
target.addComponent(counterLabel);
}
});
}
The line has super(new CompoundPropertyModel(this)); gives a compiler error. I
replaced it with the following:
super();
setDefaultModel(new CompoundPropertyModel(this));
and it works.
My question is:
1. Am I doing the right thing?
2. Any better or more elegant way?
3. How much of WIA remains true as far as Wicket 1.4.5 concerned?
Thanks!
