Hi
I have a class with a property being a Set of generic type declared similar to this.
Code:
public class Batch<T extends Item> {
@NotNull @Valid
private Set<T> items;
}
When I try to validate an instance of Batch class, I get the following error:
Code:
javax.validation.UnexpectedTypeException: No validator could be found for type: T

Is this by design or is there any way to validate generic typed properties?
