javax.persistence.PersistenceException: org.hibernate.exception.ConstraintViolationException

Hi,
It seems you did not map the formOutput data correctly. When a ConstraintViolationException is raised the violations are shown as [attribute1] is required or something.
Check this and correct your form.
Bye

Thank you, appreciate your help. I am very new to this tool.
