OAF customizations are not working after upgrade from R12.1.3 to R12.2.10
We upgraded Oracle application from 12.1.3 to 12.2.10 and OAF customizations are not working after the upgrade. It is not working for any module. Profile options are verified. Exported customization from 12.1.3 and imported again to 12.2.10 successfully but still it is not working. We are able to see the customizations in the MDS repository in 12.2.10. Anyone experienced this issue? We are planning to start next upgrade for CRP but this is show stopper for the next upgrade? Opened SR with support but not getting any solution.
