>                 URL:
>             Project: BVal
>          Issue Type: Bug
>          Components: jsr303
>    Affects Versions: 0.4
>         Environment: JDK 1.6, Windows, Eclipse 3.7
>            Reporter: Sascha Vujevic
>         Attachments: ValidationTest.jar,
> In the Test i have attached i have a @Size-Constraint on a method for validation of the
returnvalue. In version 0.3 of bval-jsr303 it worked.
> In version 0.4 there is a change in the code:
> The method org.apache.bval.jsr303.extensions.patchFactoryContextForMethodValidation is
no longer activ. Therefore all Jsr303MetaBeanFactory were no longer changed to MethodValidatorMetaBeanFactory.
> This has the affect that the method hasValidationConstraintsDefined() is used from Jsr303MetaBeanFactory
which checks if there is a Constraint on the Method. If it is, a exception is thrown "Property
%myMethod% does not follow javabean conventions".
> Mayby i use the annotions for validating returnvalues in a wrong way.
> I have attached an example.
> Thank you for your help.
