rowKey function threw; falling back to index identity for the affected rows.

Since

1.0.1

What happened

The rowKey function threw for a row, so that row is keyed by its index instead. An index key is not stable across a sort, a filter or a reload, so selection, editing and live updates on that row will behave as though it had no key at all.

The fix

The error is attached to the console line. The function is called for every row, including ones whose fields are missing.
