You are putting view objects inside the model of other view object. Models
are meant to keep your application domain data, and over that you create
your view. So:
For what MyPanel was designed?
1 - For present MyData
container.add(new ListView<MyData>("panels", panels) {
protected void populateItem(ListItem<MyData> item) {
item.add( new MyPanel("panel", item.getModelObject()));
}
});
then you write:
panels.getModelObject().add(new MyData());
more some code to update panels like
target.addComponent(container);
2 - For present some static markup on template
so consider to use an less sophisticated repeater, like RepeatingView
