Hi all,
I am using grails 1.3.5 and the latest app-engine and gorm-jpa
plugins. I created a User class and a UserIntegrationTest to test it.
However, I am getting a error in the reports:
****
Could not open JPA EntityManager for transaction; nested exception is
java.lang.NullPointerException: No API environment is registered for
this thread.
org.springframework.transaction.CannotCreateTransactionException:
