i have written a validator to check the duplicacy in the multi value attribute called "Production Plant" in both create and checkout and edit page...But i could accomplish this only in create page.

Since "create" action default validator is DefaultUIComponentValidator. i created a validator extending it.

For "checkoutandEdit" action default validator is CheckoutAndEditValidator. i created another validator extending it.

PFA the java files. But the problem is that it works for create acton but not checkout functions.

Need help with this
