    Problem in fetching cmr field in jboss3.0

    iso Newbie

      Hello,

      We are using JBoss3.0 Alpha from Nov. 21, 2001. we just deployed two simple entity beans with one to one bidirectional relationship, we are able to set the cmr field successfully, however we got an error on getting the cmr field value. Following is the exception

      [09:56:22,114,LogInterceptor] TransactionRolledbackException, causedBy:
      javax.ejb.EJBException: Internal error setting instance field id:

      We also tried one to many relation. We got the same exception when we tried to get the single object through cmr field, however, getting collection was not a problem.
      Can someone help us on this?


      Thanks,
