Greetings,
Please I have some further questions to ask about models.
LoadableDetachableModel cannot be used as a CompoundPropertyModel obviously
meaning that if I load an Object with LoadableDetachableModel , I cant
simple pass the LoadableDetachableModel to a Label so that the Label can use
its id to resolve the value,
Which means I have to first get the Object from the LoadableDetachableModel
before wrapping it into CompoundPropertyModel again or a PropertyModel
Please help me out;
class MyData {
Long id;
String name;
String address;
String info;
}
class MyDataModel extends LoadableDetachableModel {
Long id;
public Object load(){
return dao.getData(id);
}
}
MyDataModel mymodel = ...;
Label nameLabel = new Label("name", mymodel);
Label addressLabel = new Label("address, mymodel);
Label infoLabel = new Label("info", mymodel);
because i see so many codes like this:
Label label = new Label("name", new AbstractReadOnlyModel() {
public Object getObject(Component component) {
return someobject.getName();
}
});
1. why create another Model
2. to retreive my someobject from another model to use in another model just
to display does yet seem nice to me
so why can that single instance of LoadableDetachableModel which is a
readonly model be very handy for so many Label components knowing fully well
that Websites are filled with labels loading from a Data Object.
shoot me somebody :)
am still using 1.2.6 please, is it time to move to 1.3?
