Quoted from the thread mentioned: You are going to need to provide Spring MVC with a way to get from an id to a country and vice-versa. As you correctly point out this is done by registering a custom property editor in your controller. To do this you need to:
1) Extend the class PropertyEditorSupport to create the property editor: http://java.sun.com/j2se/1.5.0/docs/api/java/beans/PropertyEditorSupport.html You need to override the getAsText() and setAsText() methods. The first should call getValue() and return the id as text, and the second should accept a text id and call setValue() on the editor with the corresponding country object. 2) You then register this custom editor using one of the appropriate methods on your controller: initBinder() see api on http://tinyurl.com/2sutrm And it should all work like magic....

Thanks Mike for your reply. Actually i am not getting a clear idea about how to implement PropertyEditorSupport Class excatly in my form controller. It will be very helpful if u can explore about it a bit more.
