[hibernate-issues] [Hibernate-JIRA] Issue Comment Edited: (HHH-5267) NPE on Cascade after switch to hibernate 3.5

NPE on Cascade after switch to hibernate 3.5 -------------------------------------------- Key: HHH-5267 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5267 Project: Hibernate Core Issue Type: Bug Components: annotations, core Environment: Hibernate 3.5.x Reporter: Krzysztof Kowalczyk Priority: Blocker We use hibernate annotations and hibernate search in our project. After we moved to hibernate 3.5.2 (and 3.5.1 before that) we are having the following errors: java.lang.NullPointerException at org.hibernate.engine.EntityEntry.getLoadedValue(EntityEntry.java:255) at

at org.hibernate.impl.SessionImpl.saveOrUpdate(SessionImpl.java:669) [java] at org.hibernate.impl.SessionImpl.saveOrUpdate(SessionImpl.java:665) The NPE is thrown because "loadedState" field is null. The exception seems to occur for instance when we have OneToOne with Cascade.DELETE_ORPHAN (or orphanRemoval="true"), CascadeType.SAVE_UPDATE and CascadeType.DELETE. I will try to create a simple example to reproduce the problem.
