And don't forget final scopes:
final Thing thing = component.getModelObject();
add(new Label("this", "that") {
@Override
public boolean isVisible() {
return thing.isGreen();
}
});
For the object "thing" to be accessible in the anonymous inner class
it had to be declared final. Because the Label's isVisible() method
accesses thing, the Label has a reference to thing and thus thing will
be serialized with the Label.
