Hi Greg,
Please take a look at this community post for an explanation of why this is happening:
https://community.skuid.com/t/upgraded-to-summer-ga-and-this-line-now-prevents-a-skuid…
To avoid this, you’ll need to change this line:
field.model.updateRow(
field.row,
modifications
);
to this:
field.model.updateRow(
field.row,
modifications,
{ initiatorId: field._GUID }
);
