One to many relationships throwing a Excetion --------------------------------------------- Key: JBAS-3850 URL: http://jira.jboss.com/jira/browse/JBAS-3850 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: CMP service Affects Versions: JBossAS-4.0.5.GA Environment: Windows XP, JBoss 4.0.5GA, JBoss 4.0.4GA and JBoss 3.2.8.SP1 AMD Sempron 3000+ 2.00 GHz 512 Mb RAM Reporter: Santiago de la Nava Santos Assigned To: Alexey Loubyansky Hi all, I'm having a similar problem with one to many relationship, CMP persistence and EJB 2 specification. I have tested the problem at versions 3.2.8.SP1, 4.0.4.GA and 4.0.5.GA, and they all throws the same Exception. I have an ExperimentEJB that is related to many ConfigurationEJB. When I try to add the ConfigurationEJB Collection to ExperimentEJB, the system throws this exception: 11:07:01,323 ERROR [LogInterceptor] RuntimeException in method: public abstract void softiam.services.ejbs.experiment.Ex periment.setConfiguration(java.util.Collection) throws java.rmi.RemoteException: java.lang.NullPointerException at
