DropDownChoices where Model is different from Data

Hi. 
I have a form model containing a idKey that is supposed to be selected from
a dropdownchoice. Does anyone know if its possible have a complex data type
in the dropdownchoice when the model is only a idKey? The dropdownchoice
wants to set the complex data type in the form model. 
For example in a dropdownconstructor:
public MyDropDown(String pId,PropertyModel<UUID> pModel){
super(pId,new LoadableDetachableModel<MyClass>(){

       protected List<MyClass> load() 
       {
           return requestClasses();
       }

})
setChoiceRenderer(new ChoiceRenderer<Myclass>("displayName", "idKey"));

would It be possible to link the pModel in another model (SpecialModel) to
accomplish this? Like: setModel(new SpecialModel(pModel));

Tanks Nino. Just checking if I was out in the blue. I'll try to do something
with my chained model.

Hi

since it's java development, the only limit are your mind (now all your 
ruby guys dont hit me).. As you write yourself just create a 
choicerenderer, then choicerenderer itself can decide howto display data..

And yes if you chain stuff and implement your own model etc you can do 
it all your own way..
