How to save a property which value comes from a join() collection?

[GalinhaLX]

Hi

When I have a property which value (trought mv-value, or inside innerHTML) comes from a collection, that I join()
-> I'm unable to save this property data

Do I need to replace some characters inside value, to be able to save it? Or is this a bug?

My codepen here:

Solved

Need to use mv-default
mv-default="[join(myList.name,' ')]"

Codepen is also corrected to reflect answer

Note that this would also make it editable. If you don't want that, you can specify mv-storage="auto" and it will be saved :)

I've used mv-storage="inherit" to force saving of mv-values; what does auto do and how does it differ?

Just a typo, it should be inherit.
