after troubling many people here, and thankful for their help, here is the
CompositeComponent component.
you just overwrite two methods, and voila!
hope it is useful for someone else.
it is part of the product i'm working on, so it's MPL licensed.
public abstract class CompositeComponent extends FormComponent{
public CompositeComponent(String id) {
this(id, null);
}
public CompositeComponent(String id, IModel model) {
// XXX: can make it in omModelChanged, but then i have to do
some ugly checks
super(id);
setModel(new PartialModel(model));
}
abstract protected String[] getCompositeInput(List<String[]> list);
abstract protected Object getPartialObject(Component component, Object
modelObject);
/* (non-Javadoc)
* @see wicket.markup.html.form.FormComponent#getInput()
*/
@Override
public String[] getInputAsArray() {
// go over all children, and create a list.
final List<String[]> list = null;
visitChildren(FormComponent.class, new Component.IVisitor(){
public Object component(Component component) {
list.add(((FormComponent)component).getInputAsArray());
return Component.IVisitor.CONTINUE_TRAVERSAL;
}
});
return getCompositeInput(list);
}
private CompositeComponent getThis() {
return this;
}
private class PartialModel implements ICompoundModel {
private IModel selfModel;
public PartialModel(IModel model) {
selfModel = model;
}
public IModel getNestedModel() {
return null;
}
public Object getObject(Component component) {
resolveSelfModel();
return getPartialObject(component,
selfModel.getObject(getThis()));
}
public void setObject(Component component, Object object) {
if (component == null) {
resolveSelfModel();
selfModel.setObject(getThis(), object);
}
}
private void resolveSelfModel() {
if (selfModel == null) {
selfModel = getParent().getModel();
}
}
public void detach() {
// TODO Auto-generated method stub
}
}
}
