edit is enabled but the {adapter} adapter declares mutate: {false|without update} (read-only by declaration), so no commit is synthesised and the grid stays read-only. Declare `mutate: { update: true }` on the adapter to allow cell edits.

The grid (core)

Since

1.23.0

What happened

Editing was configured over an adapter that declares itself read-only. No commit hook is synthesised, so the grid stays read-only rather than accepting edits that could never be persisted.

The fix

Declare mutate: { update: true } on the adapter, or supply your own edit.commit.
