I'm looking into this myself. Are you using read-only methods by any chance?

Got 5 hits this weekend. Other fields always correspond to the context with the expected primary key. i.e. entityContext.getEJBLocalObject() returns a consistent entity but belonging to the context other than current.

I did not check yet for other fields. I will do it now and see. But it will take some time until our next development iteration is finished and released. As I said, I perform the check inside one of business methods of the entity bean:
public abstract class TerminalBean extends MMSBean implements EntityBean { [...] public TerminalDO getTerminalDO() { //todo: remove when fixed TerminalPK pkViaEc = (TerminalPK)entityContext.getEJBLocalObject().getPrimaryKey(); TerminalPK pkViaGetters = new TerminalPK(getVendor(), getModel()); if (!pkViaEc.equals(pkViaGetters)) { logger.error("pkViaEc="+pkViaEc+", pkViaGetters="+pkViaGetters); } //entityContext.getEJBLocalObject().getPrimaryKey() is buggy and sometimes returns primary key of //another object return new TerminalDO(new TerminalPK(getVendor(), getModel()), getPropertyDOs(), getDescription(), getModel(), getVendor()); } [...] }
Another case for me is when customer is authenticated on the site, I save the ejb handle of Customer bean in servlet session. After that to obtain a local interface of the Customer Bean I use
Customer customer = (Customer)((CustomerRemote)handle.getEJBObject()).getLocalObject()
where getLocalObject() is implemented as a business method
public EJBLocalObject getLocalObject() { return entityContext.getEJBLocalObject(); }
At this point I get the local interface of another customer (not the one the handle points to).
After that I again use the customer.getPrimaryKey() of the customer in further business logic...
I will install the check of other fields and let you know.

Hello Alexey,
what about other fields? Do their values correspond to the context with the expected primary key or to the context that is actually present?
When do you perform the check? More details would really be appreciated.
Thank you, alex

Sometimes they do not match: entityContext.getEJBLocalObject().getPrimaryKey() returns primary key of another instance of the same entity bean.
