    Remove method fails with composite PK

    Janis Newbie

      Hi,

      I'm working with JBoss 2.4.9/Tomcat 4.0.4 and Oracle8i database.
      I created CMP bean with composite PK, that contains two arguments - String and Long. All methods works fine, except remove method. The same application works fine on JBoss 2.4.4.

      Here is my code:
      Collection subs = subscriptionHome.findByEmail(email);
      Iterator it = oldSubscription.iterator();
      while (it.hasNext()) {
      ((Subscription)it.next()).remove();
      }

      Here is the stack trace:
      javax.transaction.TransactionRolledbackException: Load failed; nested exception is:
      java.lang.IllegalArgumentException: object is not an instance of declaring class; nested exception is:
      java.rmi.ServerException: Load failed; nested exception is:
