Radio does not accept null values (similar for checkbox & select)

Describe the bug When using null values in options-prop, the inputs fallback to HTML default behavior as if no value was set.

I would actually expect, that null can be used as value if explicit defined.

Maybe I’m expecting too much here, since null is not a typical value for HTML elements, but from the JS perspective I’d rather expect null than “on”.

Fair question. Vue is actually the thing making this work the way it does since it sees the null (and undefined) as a no op attribute value.

I dont think it is asking too much however — one of the goals of this project is to smooth out some of those inconsistencies and make things “just work”.

@lavolpecheprogramma new issues are generally good for new bugs, but thats one is not a bug — lists must explicitly have array values. An new list will set its own value to an array, but if the list is told to set its value to undefined or null that error will be raised.
