Thanks for the response. How do I bind the playerModel to the DDC? If I did
the below extract the object out of the playerModel it would probably work.
Player player = (Player)playerModel.getObject();
final DropDownChoice downChoice = new DropDownChoice("name", new
Model(Player), playersModel, new ChoiceRenderer("username", "id"));
If I did this though, the player object would get serialized and I want to
avoid that. If I use:
final DropDownChoice downChoice = new DropDownChoice("name", new
CompoundPropertyModel(playerModel), playersModel, new
ChoiceRenderer("username", "id"));
This would work fine w/o serialization except that the compound expects a
setter with the name of the component from the object that comes from the
backing LDM (playerModel) so it would error. I essentially want it to not
use a setter, instead just store the value itself as the object.
