[bv-dev] @ConvertGroup and inheritance

Hi all, I'm about to implement group conversion via @ConvertGroup in the RI. I'm wondering how we should deal with situations where @ConvertGroup is given for a one property of a base class and again on a sub-class (same for interface and impl): public class Foo { @Valid @ConvertGroup(from=Default.class, to=AnotherGroup.class) Bar getBar() { ... } } public class Baz extends Foo { @Override @Valid @ConvertGroup(from=SomeGroup.class, to=YetAnotherGroup.class) Bar getBar() { ... } } AFAICS we've got the following options here (in descending order of my preference): * Merge all the conversions for a property from the hierarchy (so behavior is the same as when all conversions would have been given in one place using @ConvertGroup.List) * Consider only the top/bottom most conversion rule from the inheritance hierarchy * Allow only one conversion for a property in the hierarchy, throw an exception if multiple conversions are given Any thoughts? --Gunnar
