Yup thats right. But after that you use that CarPart object raw. When
you provide it to the components...
final CarPart carPart = (CarPart) item.getModelObject();
which is load() object correctly - i tested it by quickly putting:
@Override
protected Object load() {
System.out.println("\n\n\n LOAD object: " +
this.carPartId + "\n\n\n");
return carPartService.getCarPartById(this.carPartId);
}
for 3 elements on the page I got in logs:
LOAD object: 13
LOAD object: 12
LOAD object: 2
So I think deatachable model is used here? Am I wrong?
I believe youre wrong.
item.add(price = new Label(PRICE, carPart.getPrice().toString()));
Carpart is not a detachable model right?
and further more, toString isnt..
If I want to use item.setModelObject(new
CompoundPropertyModel(carPart)); how can I get netsted object in:
carPart.getCarModel().getModelName()
Something like this: new
PropertyModel(myCompoundPropertyModel(mydetachableModel).bind("carModel"),"modelName");
It's very important that you chain the models, otherwise you'll still
not use the detachablemodel... Like my previous example:
item.setModel(new CompoundModel(item.getModel()));
