True, this is also what I am thinking about doing...

If you dont want to use an original object why not just clone/create a
copy of the original end use that and then copy the values over again?
(i think beanutils or something van do that for you)

Hi
Im trying todo a compoundpropertymodel which does not change original
values in the "original" model. I need this since I am updating some
stuff in a wizard but I first want to commit when the user confirms in
the end of the wizard, and if the model are changed directly the
transaction are automatically committed to the database....
So my idea were to todo a shadowCompoundPropertyModel something like this:
class EditorModel extends CompoundPropertyModel {
private Map newValues=new HashMap<String, Object>();
public EditorModel(CompoundPropertyModel underlyingModel,
String propertyName) {
super(underlyingModel);
}
public getObject (String property){
check if there are something in the map if so return it, otherwise fall
back to the underlying model
}
public setObject (String prop, Value){
put changes in the map...
}
public UpdateOriginal(){
iterate over the map and use reflection to set values on the original
model..
}
}
Does anybody have something similar floating around, in a more complete
state..? Or could it be done in a easier way?
