Hi Dave,
Please find the patch in attachement with below changes.
--- Changed the UI design and make it consistence with dlgTable.
When user creates the view then user has option to create Normal View Or Materialized View.
User is not allowed to change the "Security Barrier" and "Materialized View" at the same time because "Security Barrier" option is for Normal View.
So we put the below message
"Security barrier and materialized view can not be enbale at the same time"
Let me know if any modification is required.
Thanks,
Neel Patel
