I'm trying to default a DDC (DropDownChoice) using the model I am passing
in. The page is getting passed in a LoadableDetachableModel which is of
Type Player. The list to back the DDC is a List<Player>.
LoadableDetachableModel playersModel = new LoadableDetachableModel()
{
protected Object load()
{
return playerManager.getPlayersInLeague(getActiveLeague());
}
};
And here is the DDC.
final DropDownChoice downChoice = new DropDownChoice("name", new Model(),
playersModel, new ChoiceRenderer("username", "id"));
add(downChoice);
downChoice.add(new AjaxFormComponentUpdatingBehavior("onChange")
{
@Override
protected void onUpdate(AjaxRequestTarget target) {
setResponsePage(new ViewPicksPage(downChoice.getModel()));
}
});
The above code works but does not obviously does not default the DDC. I
want the default to be the playerModel that is being passed in to the page.
If I pass the playerModel into the DDC (instead of the new Model()) I get an
error saying that I can't set a model on a LDM (loadabledetachablemodel).
What is the correct way to default the DDC? I've read that I shouldn't use
a LDM for backing as it is loadable, but then what model should I use? Keep
in mind that I am trying to keep the memory footprint low and do not want to
serialize objects unless I have to.
