Registering custom property editors in spring

Question

This is regarding Spring property editors. I have a Interface A that is being implemented to Class B and C. I have a command class Doc in which in which i have a list of A

class Doc{
List<A> list ;
}

list may contain either object of B or C. In this situation how could i use property editor. i wrote two property editor for the two classes and register them in initBinder method as

binder.registerCustomEditor(C.class,new CPropertyEditor());
 binder.registerCustomEditor(B.class,new BPropertyEditor()); 

but it does not seems to be working. Please help.

i am getting the following exception:

Request processing failed; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [com.test.A] for property list: no matching editors or conversion strategy found

This is my first post so please sorry if i made any mistake.

Answer 1

One approach is to implement a single property editor for A. The implementation can look at the string and then create an instance of B or C.
