Yes I just managed the same.
THe process is
- Export the affected template using the native json option and open this in a text editor, search for EVENT_CONTEXT then remove the adjacent
"nodeId": "at0002"line.
The ‘category’ attribute is not included in the native json template so there are no other edits required, as far as I can tell.
-
Import the corrected version of the Composition archetype, which has had the erroneous atCodes and terms removed.
-
Import the corrected native json template, making sure you allow overwrites.
