Question

Little problem with DropDownChoice.
I build a DropDownChoice with a list of Object.
Take for example:

public MyClass 
  private String code;
  private String description;
[...]

than take another Object

public FormModelObject
   private String code;

I can easly build the DropDownChoice selecting what show (description property) and what obtain (code property) using ChoiceRender.

Unfortunally the DropDownChoice return the entire Object (MyClass) and I cannot set the property Code inside FormModelObject (it simply launch a toString() method on MyClass).

How can I obtain it without using Ajax?

Thanks

Well, you could override method onModelChanged() of DropDownChoice and update residenceZipCode with the new value. Something like :

DropDownChoice<City> drop = new DropDownChoice<City>("residenceZipCode",new Model(), cityList,new ChoiceRenderer<City>("name", "zipcode")){
     onModelChanged(){
       String newZipCode =  (String)PropertyResolver.getValue("zipCode",getModelObject());
       PropertyResolver.setValue("residenceZipCode", res, newZipCode, new  PropertyResolverConverter());
     }

};

DropDownChoice must have its own model.
