--------------------------------------
Component/s: (was: jackrabbit-ocm)

Workflow: no-reopen-closed, patch-avail (was: jira)
Key: OCM-8 (was: JCR-1928)

> Cannot use @Collection on getters
> ---------------------------------

> Key: OCM-8
> URL: https://issues.apache.org/jira/browse/OCM-8
> Project: Jackrabbit OCM
> Issue Type: Bug
> Reporter: Yoav Landman
>
> I have a class with no mapped fields that has a collection reference. With JR
> 1.4.x, I use to use a collection mapping like this on the getter:
> @Node(extend = OcmStorable.class)
> public class User implements OcmStorable {
> @Collection(elementClassName = String.class, collectionConverter =
> MultiValueCollectionConverterImpl.class)
> public Set<String> getGroups() {
> return info.getGroups();
> }
> public void setGroups(Set<String> groups) {
> info.setGroups(groups);
> }
> }
> With 1.5 this crashes with:
> Caused by: org.apache.jackrabbit.ocm.exception.InitMapperException:
> Impossible to read the mapping descriptor from the getter for class : class
> org.artifactory.security.User for field : groups; nested exception is
> java.lang.NoSuchFieldException: groups

> Looks like
> org.apache.jackrabbit.ocm.mapper.impl.annotation.AnnotationDescriptorReader#216
> is passing:
> propertyDescriptor.getPropertyType().getDeclaredField(propertyDescriptor.getName()),
> and propertyDescriptor.getPropertyType() is, in fact, java.util.Set (so of
> course no 'groups' field).
> As a workaround, I have to use a dummy field, annotate it and let the getters
> and setters work as before.
> Thanks.
