You'll have to trace through your code. Looks like you're not using a real pk value.






Come meet me at the LSNA!

vikash kumar:

how to use real pk

Please show us the code you use when you get the mentioned error message. If you update a custom entity, that entity should have a proper id, so that it's clear which object should be updated.

Thanks for the code - you could make it easier to read (and motivate others to answer) if you used the formatting options.
That being said, your error message states a problem in EmployeePersistenceImpl:706, which you don't post. From the code that you posted, it seems odd that the "addEmployee" uses an id that's provided by the UI: A new id should be provided by the underlying persistence layer. And if your addEmployee.
Let us know what kind of code you have in EmployeePersistenceImpl, line 706, especially what message that's in. You might just want to set a breakpoint there and inspect the values and the callstack yourself.
