Sorry in case this has been asked before, but all discussions I found seem to be not relevant or deal with a different issue.
Using APEX 18.1, in my page I have a region which is using a dynamic region title:

This works ok for the initial page load, but not if I would like to refresh the region title later.
Looking thru various posts, I understand that a region refresh does only refresh the content of the region. How would I refresh the title ?
I tried:
- Setting P11_CODE_ID does set the session value, but does not refresh the title
- Using DA to refresh Selection Type JQuery Selector h2#error_pie_heading.t-Region-title
(region has static id "error_pie")

Would this be the right approach ?
Thanks
