We have make a quick fix for this, it's not nice, maybe you can fix it in the next version public class SearchFactoryImpl implements SearchFactoryImplementor { ... private void initDocumentBuilders(SearchConfiguration cfg, ReflectionManager reflectionManager) { ... //if ( mappedXClass.isAbstract() ) { //      log.warn( "Abstract classes can never insert index documents. Remove @Indexed." ); //      continue; //} ... } ... Set<Class<?>> getIndexedClasses(Class<?>[] classes) {          Set<Class<?>> idexedClasses = new HashSet<Class<?>>();          for ( Class clazz : classes ) {             Inheritance inheritance = (Inheritance) clazz.getAnnotation(Inheritance.class);             if(inheritance!=null && inheritance.strategy().equals(InheritanceType.SINGLE_TABLE))             {                idexedClasses.add(clazz);             }             else             {             Set<Class<?>> set = classToIndexedClass.get( clazz );             if ( set != null ) {                // at this point we don't have to care about including indexed subclasses of a indexed class                // MultiClassesQueryLoader will take care of this later and optimise the queries                idexedClasses.addAll( set );             }             }          }          if ( log.isTraceEnabled() ) {             log.trace( "Targeted indexed classes for {}: {}", Arrays.toString( classes ), idexedClasses );          }          return idexedClasses;       } ... } -- Zhendong Chen ----------------------------------------------------------------------------------------------------------------- PDS Programm + Datenservice GmbH Mühlenstrasse 22 - 27356 Rotenburg (Wümme) Telefon: (04261) 855-01, Fax: (04261) 855-335 E-Mail: zhendong.chen(a)pds.de, Homepage: www.pds.de Geschäftsleitung: Hinrich Hamelberg, Stephan Mau, Handelsregister Walsrode HRB 70186, Steuer-Nr.: 40/202/02809, USt-IdNr.: DE 116324331 _______________________________________________ hibernate-dev mailing list hibernate-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
