I'm running a Grails application in "PRODUCTION ENV." with version 2.3.1. It runs fine for some time. But after some time, it starts failing with exception "InvalidDataAccessApiUsageException". Again when I delete target folder and re run the application, it works good.
There is no error while working in "DEVELOPMENT ENV".
Detailed exception is
[[ErrorType:class org.springframework.dao.InvalidDataAccessApiUsageException],
[ErrorMessage:The given object has a null identifier: com.test.model.Test;
nested exception is org.hibernate.TransientObjectException:
The given object has a null identifier: com.test.model.Test]]
