I debugged it further (no success yet)
In SimpleViolation.java, following code is able to find 3 matching
delegates for 1 property:
public static void pushViolations(Iterable<SimpleViolation> violations,
EditorDriver<?> driver, KeyMethod keyMethod) {
if (violations == null) {
return;
}
DelegateMap delegateMap = DelegateMap.of(driver, keyMethod);
// For each violation
for (SimpleViolation error : violations) {
Object key = error.getKey();
List<AbstractEditorDelegate<?, ?>> delegateList = delegateMap.get(key);
*delegateList* above has 2 or 3 editors depending on my configuration.
Probable reason is because subType has access to all superType properties
so subType editor driver can be considered a delegate for that property.
SuperType's editor is a delegate in itself. Since everyone implements
Editor<? extends T> everyone is responsible for setting violations. For
every editor involved, it pushes violation to same textbox which shows
violation multiple times.
Is this expected? If yes, how to correctly use Editor framework for
polymorphic types and display ConstraintViolation only once?
Thanks,
Arpit
