Hi all,
After activating the "hibernate.cache.auto_evict_collection_cache" property, I am getting this error on saving entities updates.
Quote:
org.hibernate.HibernateException: Unable to resolve property:

I think that the problem is when checking for the mappedBy property on a collection persister: when empty, It returns an empty string instead of null.
The error is thrown by the following lines in
org.hibernate.cache.internal.CollectionCacheInvalidator.java:
Code:
// this is the property this OneToMany relation is mapped by
String mappedBy = collectionPersister.getMappedByProperty();
if ( mappedBy != null ) {
int i = persister.getEntityMetamodel().getPropertyIndex( mappedBy );
...
}
Is this an Hibernate issue ?
Thank you.
Note: I am using Hibernate 4.3.5.Final with JPA 2.1.
