Oracle.jbo.PersistenceException

Question

Hi,
I am getting PersistenceException on AO when EO is modified.
The scenario is like:
1. Two Base table were altered to add new columns.
2. To reflect these newly added columns, EOs were synchronized.
3. The VOs based on this EOs were also modified to embed the newly added columns.
4. No change was done on AO based on these two EOs.
When I run the page whose VO uses this AO as read only and reference and try to create a new record it gives oracle.apps.fnd.framework.OAException: oracle.jbo.PersistenceException: JBO-26031.
The exception stack trace is as follows:
oracle.apps.fnd.framework.OAException: oracle.jbo.PersistenceException: JBO-26031: Assocation end xxcustInstMasterEO of assoc xxcustTdsMasterToInstAO invalid for entity base xxcustInstMasterEO in view object xxcustTdsMasterVO.

Do I need to delete this AO and re-create this AO...?

Answer 1

The issue got resolved. I am sure about the solution but seems like it had to do something with embedded oc4j server.
After modifying the EOs and related VOs, the embedded OC4J server was not terminated due to which the modifications were not reflected (assumption).
I did not make any changes to AO and now its working perfectly fine.
Thanks,
