Thanks for your reply. I created a similar solution. In any case consider to expose a JS API, I think would be helpful for custom solutions.
thanks! while the sequence is first the postID and then the meta 🙂
Found the on_sent_ok: and works fine. 🙂
I have the same issue with v3.5.4.1 and WordPress 3.5. The data are saved in the database but they are not visible in the “Edit Field Group”.
Field Groups I have created are visible and the number their fields in the right side. But when I click on the Field Group then I get “No fields. Click the + Add Field button to create your first field.”
Let me know if you want to provide you more information.
