Antonio Goncalves commented on FORGE-1582:
------------------------------------------

I've been trying to create a Bean Validation constraint properly... in vain. What I want to achieve is the following (notice the @List annotation) :

{code}
@Target({METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER})
@Retention(RUNTIME)
@Documented
@Constraint(validatedBy = {})
public @interface Email {

  String message() default "wrong email address";

  Class<?>[] groups() default {};

  Class<? extends Payload>[] payload() default {};

  @Target({METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER})
  @Retention(RUNTIME)
  @interface List {
    Email[] value();
  }
}
{code}


This is the code I've written. Both annotation are generated separately... but I don't know how to add listAnnotation inside emailAnnotation. Any idea ?


{code}
public class Main {

    public static void main(String[] args) {

 
        // This is the inner annotation List

        final JavaAnnotationSource listAnnotation = Roaster.create(JavaAnnotationSource.class);

        listAnnotation.setName("List");

        listAnnotation.addAnnotation(Retention.class).setEnumValue(RUNTIME);

        listAnnotation.addAnnotation(Target.class).setEnumValue(METHOD, FIELD, PARAMETER, TYPE);

        listAnnotation.addAnnotationElement("Email[] value()");

        System.out.println(listAnnotation);

 
        // This is the annotation @Email

        final JavaAnnotationSource emailAnnotation = Roaster.create(JavaAnnotationSource.class);

        emailAnnotation.setPackage("org.agoncal.proj.constraints").setName("Email");

        emailAnnotation.addImport(Payload.class);

        emailAnnotation.addAnnotation(Documented.class);

        emailAnnotation.addAnnotation(Retention.class).setEnumValue(RUNTIME);

        emailAnnotation.addAnnotation(Target.class).setEnumValue(METHOD, FIELD, PARAMETER, TYPE);

        emailAnnotation.addAnnotation(Constraint.class).setLiteralValue("validatedBy", "{}");

        emailAnnotation.addAnnotationElement("String message() default \"wrong email address\"");

        emailAnnotation.addAnnotationElement("Class<?>[] groups() default {}");

        emailAnnotation.addAnnotationElement("Class<? extends Payload>[] payload() default {}");

        
        // I was expecting to have a method like that so I could add annotation inside another one

        // emailAnnotation.addAnnotationElement(emailAnnotation);
        

        System.out.println(emailAnnotation);

 
    }
}
{code}
