Can anybody kindly please tell me how to create ItemKeyGenerator.
I have to manipulate with many objects (including wrappers).
I am getting "Inconsistent state for failed item key: hashCode has changed. Consider whether equals() or hashCode() for the item might be inconsistent, or if you need to supply a better ItemKeyGenerator" for exceptions.
I really stuck with this.
It will be very helpful if anybody can help me on this?
