Describe the bug

Select component seems to accept numbers, and given this type definitions

export type Key = string | number;

export type Selection = 'all' | Set<Key>;

onSelectionChange?: (keys: Selection) => any,

it indeed seems possible. However, when you provide numbers as items of Select, in onSelectionChange, keys is always Set<string>

            console.log(v);
          }}
        >
          {(item) => (
            <SelectItem key={item.value} value={item.value}>
              {item.label}
            </SelectItem>

ENG-775 [BUG] - Select not working correctly with numbers

Additionally, when you provide string[] to selectedKeys, e.g. [2020, 2021], then it cannot find these keys, therefore the Select dropdown does not show ticks next to selected items.

Thanks for the issue!

This issue stems from React converting the key to a string.

Note that if you do specify a custom key on each Item using the key prop, React will convert the provided key to a string. As a result, all the collection component's key-related event handlers and props (e.g. onSelectionChange, selectedKey(s)) will expect and return strings.

See: https://react-spectrum.adobe.com/react-stately/collections.html#unique-keys

While it can be resolved by assigning an id to items as shown below, but the current situation requires a key, so some adjustments need to be made. I'm currently working on this fix.

let [years, setYears] = useState([
  {id: 1, value: 2024},
  {id: 2, value: 2025},
  {id: 3, value: 2026}
]);

<Select items={years}>
  {item => <SelectItem>{item.value}</SelectItem>}
</Select>
