upgrade apex 41 to apex 425 issue ora-01400 ARP DML automatic row processing

automatic row processing dml not working after upgrade apex 41 to apex 425 After upgrade from apex41 to apex425 we experience that ARP dml is not working properly. We loose variable information, so the insert fails. Error Codes : ORA-01400 This was to a bug : In our case the page item property was Display Only.  We set save session state to YES.  It solved the problem.
