Hmm, I’m not sure exactly why this wouldn’t be working, but I suspect that the issue is that the Ui-Only Model’s row Id isn’t the same as it’s “Id” field value. You might try finding the row to remove by finding the model row with a specific field value, and then using abandonRow(), which takes a row as an argument rather than a field, like this:

var rowToRemove = mod.getRows().find(function(row) {

    console.log("row.Id = " + row.Id);

    return row.Id === caseId;

});

if (rowToRemove) {

    mod.abandonRow(rowToRemove);

}

That seemed to work. Thank you!
