I believe this is the same problem as the one I reported in the old support forum.
As i mentioned, when I publish the post
A) update_value() receives the value,
B) data is stored in “prefix”_postmeta table:
select * from dev_postmeta where meta_key = 'dato' ORDER BY meta_id DESC LIMIT 1;
returns the correct value in meta_value (‘dato’ is the field name)
select * from dev_postmeta where meta_key = '_dato' ORDER BY meta_id DESC LIMIT 1;
returns the correct field_”number” in meta_value
C) create_field() creates an empty field on reload after the publish post
