so you have
Panel
SubPanel1
SubPanel2
all three of them have a LoadableModel
and the 2 subs depend on the Parent panel?
But does the parent panel itself do anything with the data?
do you call getModelObject on it? or getModel().getObject() ?
if not that you dont need to give that panel the loadable model
If you say that the 2 subs need models and those depend on the parent model
then you could give the SubPanels a model like this:
public class MySpecialSubPanelModel
{
MySpecialSubPanelModel(LoadableModel parentModel) {}
getObject()
{
Object object = parentmodel.getObect()
/// do something with that object to create another object??
return otherObject;
}
}
