Can't have an @Formula attribute in an @EmbeddedId -------------------------------------------------- Key: HCANN-25 URL: http://opensource.atlassian.com/projects/hibernate/browse/HCANN-25 Project: Hibernate Commons Annotations Issue Type: Bug Affects Versions: 3.2.0 Reporter: Nicholas White If a class that will be used as an embedded id has a column that is defined by an @Formula attribute, hibernate throws a NPE. This is because the below method in org.hibernate.cfg.Ejb3Column doesn't check if the mappingColumn is null (which it is when the column is defined by a formula) before dereferencing it. public void forceNotNull() { mappingColumn.setNullable( false ); } To fix, change the method to: public void forceNotNull() { if (mappingColumn != null) { mappingColumn.setNullable( false ); } } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
