an appended row was confirmed without a server key (the adapter's mutate returned no keys and returning is not 'key'/'row'), so the row keeps its client temp key. It is persisted but cannot be addressed by its server id. Declare returning: 'key' or 'row' on the adapter so appended rows can be rekeyed.

pending.rows.append.nokey

Raised by

The grid (core)

Since

1.26.0

What happened

The append succeeded and the grid never learned the id the server gave the row, so the row keeps the temporary key it was created with. It is saved; it simply cannot be addressed by its real id - a later update or delete keyed on the server id will not find it.

The fix

Declare returning: 'key' or returning: 'row' on the adapter so the append answers with the new id.
