Когда я обновляю resource, он возвращается к List View и корректно обновляет ресурс, но на мгновение List View мигает, и консоль выдает предупреждение:
Warning: Encountered two children with the same key, `2`. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version.

Обновлениеприменяется, даже если это предупреждение появляется.В console записи до изменения и после изменения кажутся идентичными (обеим требуется id с, единственное отличие - это изменение курса):
Запись списка записей до ОБНОВЛЕНИЯ: 
Вот так я возвращаю данные об обновлении в моем httpClient:
Записи в журнале записей после ОБНОВЛЕНИЯ: 
switch (type) {
// (...)
case UPDATE:
return { data: { id, ...updateDiff } };
// e.g.: id = 2 and updateDiff = {diffProp: 'newValue'}
}
С другой сторонырука, когда я возвращаю его без id:
switch (type) {
// (...)
case UPDATE:
return { data: updateDiff };
// e.g.: id = 2 and updateDiff = {diffProp: 'newValue'}
}
предупреждение гласит: Warning: Each child in an array or iterator should have a unique "key" prop., поэтому я предполагаю, что id требуется (в соответствии с последней версией документов).
Полагаю, в момент обновления он какое-то время рендерит обе записи (?).Как это решить?
