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.
