ClassCast exception when creating Combined constraint

Description

See https://github.com/davidkarlsen/hibernate-validator/tree/HV-448 (never mind the naming of the branch - it was an old one - but changed to fit this issue).

I get

I'm not sure about HV-450, have to see how much work this is

David KarlsenMay 2, 2011 at 9:46 PM

My bad - closing.
BTW: Will https://hibernate.atlassian.net/browse/HV-450#icft=HV-450 be updated for 4.2 betas?

David, there is a problem with your custom constraint @CompositeTest. This constraint references the validator type SizeValidatorForString within the @Constraint meta-annotation. This validator is a validator for the @Size annotation, you would have to reference a validator parametrized with the @CompositeTest annotation type instead. In case you want to create a constraint which is just composed from some other existing constraints but doesn't add any own validation logic, just use an empty array for the "validatedBy" attribute of the @Constraint meta-annotation.
