hi

I'm trying to create a validator for a Set<T>, like that :
Code:
SampleClass<T extends Foo> implements SampleInterface<T>{

@CustomValidOnGenericSet
private Set<T> foos = new HashSet<T>();

}


However, I don't manage to reflect this generic type in the validator.

The only working solution I found was to completely skip the generic part:
Code:
public class CustomValidOnGenericSetValidator implements ConstraintValidator<MyValidator, Set>


this looks pretty poor, is there a way I could do it cleanly ?

If not, does it mean that it I wanted to add a validator on some generic a field, then I would have to create a validator on top of Object ?
In code, this would mean :
Code:
SampleClass<T extends Foo> implements SampleInterface<T>{

@CustomValid
private T initialT;
}

class CustomValidator implements ConstraintValidator<MyValidator, Object>{
...
}


thanks in advance

best regards
zedros

I am not sure if I got it right, but wouldn't ConstraintValidator<MyValidator, Set<?>> be what you are looking for as syntax?
However this will not make the big difference.
