@ExpressionValidator - how to set the expression correctly ?
(amount either greater than 0 or null? )
Hi,
I have the following Expression Validator:
@ExpressionValidator(expression = "amount > 0", message = "err message")
what should come in the expression if amount can be either greater than 0 or
null?

Did you try
@ExpressionValidator(expression = "(amount > 0) || (amount == null)",
message = "err message")
