Refresh or remount

React chapter 125 · AG Grid internals · source: packages/ag-grid-react/src/reactUi/cells/cellComp.tsx

The problem

Click Edit widget locally, then Replace value. The requested value changes, but the widget keeps its old internal value because changing props does not reinitialize useState.

The pattern that fixes it

Click Replace value: the widget would keep stale internal state → try its refresh method first. With Widget supports refresh checked, update the same instance; otherwise change its key to remount with the new value. A remount discards local edits.
