I have two composite keys represented by following classes:
UserAccessAreaId consisting of 'accessAreaId' and 'userId' fields
ReportAccessAreaId consisting of 'accessAreaId' and 'reportId' fields

I have then created two classes implementing TwoWayFieldBridge for these classes. Both these bridge classes creates a field named 'id.accessAreaId'.

I perform a search after successful indexing:

FullTextSession fullTextSession = Search
        .getFullTextSession(sessionFactory.getCurrentSession());
QueryBuilder qb = fullTextSession.getSearchFactory()
        .buildQueryBuilder().forEntity(ReportAccessArea.class).get();
Query luceneQuery = qb.keyword().onField("id.accessAreaId").ignoreFieldBridge().matching(198).createQuery();
FullTextQuery fullTextQuery = fullTextSession
        .createFullTextQuery(luceneQuery);
fullTextQuery.setProjection("id");
fullTextQuery.setResultTransformer(new AliasToBeanResultTransformer(
        ReportAccessArea.class));
List<ReportAccessArea> list = fullTextQuery.list();

Then I get an unexpected problem:

14:13:22,918 ERROR [org.hibernate.property.BasicPropertyAccessor] (http-localhost-127.0.0.1-8080-1) HHH000123: IllegalArgumentException in class: ReportAccessArea, setter method of property: id
14:13:22,926 ERROR [org.hibernate.property.BasicPropertyAccessor] (http-localhost-127.0.0.1-8080-1) HHH000091: Expected type: ReportAccessAreaId, actual value: UserAccessAreaId

It seems like it is fetching and trying to set an UserAccessAreaId when it should have been a ReportAccessAreaId instead.

If I change the naming of the field 'id.accessAreaId' in the ReportAccessAreaId class to 'id.aaccessAreaId' and search using that field name instead, I get no problem.

To me it looks like a problem in Hibernate Search since I can't currently see that I am causing this problem, but on the other hand I'm quite new to Hibernate Search.
