Hi!
I have this [pseudocode] that fails
@Mixins(HasMainImageMixin.class)
public interface HasMainImage {
Attachment mainImage();
void changedMainImage(Attachment attachment);
}
public class HasMainImageMixin implements HasMainImage {
interface PrivateState {
@Optional Association<Attachment> attachment();
}
@This PrivateState state;
public void changedMainImage(Attachment attachment) {
if (attachment == null) {
state.set(null);
}
}
}
@Mixins(HasMainImage.class)
public interface TestEntity extends EntityComposite, HasMainImage {
}
The following test fails
@Test
public void testRemoveMainImage() throws Exception {
try {
EntityBuilder<TestEntity> testEntityEntityBuilder =
uow.newEntityBuilder(TestEntity.class, "test1");
Attachment attachment = createAttachment();
entity.changedMainImage(attachment);
entity.changedMainImage(null);
} finally {
if (uow.isOpen())
uow.discard();
}
}
The error is
org.qi4j.api.constraint.ConstraintViolationException: Constraint violation
in
88a8fa8e-6bee-4395-898f-d34fb41560dd-0.no.webstep.retrade.rpm.server.attachment.HasMainImageMixinTest$TestEntity
for method changedMainImage with constraint "not optional(param1)", for
value 'null'
When the association attachment is annotated with @Optional it should be
possible to unset it somehow. Am I missing something, or could it be a bug?
Best Regards,
Dag
