If the selected item has an item value that is null then it is not shown

[SergeyCherman]

Issue: If items contain an item value that is null and that is the selected item, it is not being shown on load as the selected item.

Expected Behavior: If an item exists with the itemValueField as null it should be shown as selected if that is the form control/models value.

Reproduction: 2 ports exist: Tokai with id null and Vladivostok with id false. the boolean works fine, but setting the currently selected port as null does not show "Tokai".

Hi, actually null is not considered a value, therefore is not appropriate for use in ids

[SergeyCherman]

Thanks! Would this be a reasonable feature request? If not we should add it to the docs.

[edy-ap]

thanks for you contribution, let me evaluate if is reasonable add this condition for ids

[edy-ap]

or you can submit a PR and we will evaluate the convenience to integrate it, thanks

[SergeyCherman]

Sure! Can you point me to the area of the code that handles values to get me started?

[edy-ap]

You can check the setValue method, here https://github.com/ionic-selectable/ionic-selectable/blob/1d149bf14d8cb0a991eb360dd2be622e2e6af254/packages/core/src/components/ionic-selectable/ionic-selectable.component.tsx#L1296
