Joshua,
just tried your suggestion. MIxed result.
The test was:
artworks marked TK17 and TK19
exhibition selected TK21
The first action-listops worked as the action-setfield did before, TK21
added to the exhibition_id field of both TK17 and TK19.
The second action-listops worked better, only one instance of TK19 added to
the artwork_id of TK21 but TK17 missing. I my code, I would have seen two
TK19's in the field so the action-listops means I don't need the 'contains'
list operator.
$:/TLS/artwork_id is set to TK19 but maybe the second action-listops is not
being performed until both artwork tiddlers have been processed through the
first action-listops.
Still onward and upward.
