#186 Load from query with Hibernate - error

[Jacek Uznanski]

For some classes I get this error for loading data from query with Hibernate:

"org.hibernate.QueryException: could not resolve property: null of: ......
at org.hibernate.persister.entity.AbstractPropertyMapping.propertyException(AbstractPropertyMapping.java:81)
at org.hibernate.persister.entity.AbstractPropertyMapping.toType(AbstractPropertyMapping.java:75)
at org.hibernate.persister.entity.AbstractEntityPersister.getPropertyType(AbstractEntityPersister.java:3697)
at org.openswing.swing.util.server.HibernateUtils.fillInMetaData(HibernateUtils.java:171)
at org.openswing.swing.util.server.HibernateUtils.applyFiltersAndSorter(HibernateUtils.java:267)
at org.openswing.swing.util.server.HibernateUtils.getAllFromQuery(HibernateUtils.java:535)
at org.openswing.swing.util.server.HibernateUtils.getAllFromQuery(HibernateUtils.java:585)
"

This exception appears for attribute which represents entity with composite key. For such entities method ClassMetadata.getIdentifierPropertyName() returns null.
