Possible error in CSelect when using null as option value

[AnReZa]

I'm using the following code:

<CSelect label="Druckername:"
         :options="allPrinters"
         :value.sync="localClientSettings.printerAddress" />

await this.$http.get('Settings/Printers').then(d => {
    // Service returns an array of strings
    const printerList = d.data.map(n => ({ value: n }));
    printerList.unshift({ label: 'Keiner', value: null });
    this.allPrinters = printerList;
});

As soon as I add the "Keiner" entry (which should represent a non-selection), vue writes an error into the console:

vue.esm.js?a026:628 [Vue warn]: Invalid prop: type check failed for prop "value". Expected String, Number, Boolean, Array, got Object

Also, I would expect the value of localClientSettings.printerAddress to be changed to null. Instead it's getting changed to { label: 'Keiner', value: null }, which is the object I've added to my options array.

Why does that happen? Is that a bug?

Hi! thank you for this report!
There was a problem with assigning falsy value when using objects as props.

Hotfix until fix release: use 'placeholder' prop and do not use falsy values in options.
