Hi Bhupinder,
Thank you for your reply. I'm still experiencing the issue, I'm thinking of could it be that I'm performing
default set event when navigate between tabs. Basically EC1 data model is Custom BO1, while EC2 data model is Custom BO2, since these ECs are attached to the standard Account_TI, so when embedded the EC, I have do the binding, outport standard Account ID to inport EC, use this ID to filter relevant data from the custom BOs, default set event.
But since after i click Add button, without save it, it's still no save into the custom bo, when try to navigate between tabs, it will trigger the default set event again, and make the data lost or disappear.
Have you try this situation from your end?
Thanks,
Alviss
