'boolean' widget without default value behaves strangely

bug

- What is the current behavior?

A boolean field without a default defined in config.yml will initially render as false, but the field will fail the required check:

Clicking the widget twice so it turns on and back off allows me to persist a value of false.

- If the current behavior is a bug, please provide the steps to reproduce.

1. Define a field like this in config.yml:

-
  label: Awesome
  name: awesome
  widget: boolean

2. Create a new item in the collection
3. Try to publish the item

You'll get an "AWESOME IS REQUIRED" error.

For the record, specifying default: false for the field makes the problem disappear.

Because default presently doesn't work for editor components, this problem makes it hard to get the boolean widget working in that setting.

- What is the expected behavior?

That the error does not show and awesome: false gets persisted. Or that an error is thrown early because the field doesn't have a default specified. Alternatively that a distinct "undefined" state be added for boolean fields so that you could at least tell the difference between "off" and "undefined".

@erquhart/ @papandreou is this issue still valid? It's open but it looks like a fix was merged for widgets. Just looking for an issue to help out with :)

[papandreou]

@TatisLois, I can still reproduce it with [email protected]. Which fix is that?

[papandreou]

#1662 was never merged, that's probably why it didn't have an effect 😆

@TatisLois If you are still up for this, I can guide you on how to implement a simple fix for this issue.

[TatisLois]

@barthc that would be great, would love to take a crack at it

[barthc]

@TatisLois take a look at the createEmptyDraftData function, just check for boolean widgets that does not have any default value and assign a false value, that's it. Also add some comments to explain the assigment. You can DM me on gitter if you have any questions 👍

I opened a PR in #2525. Reviews are welcome 😊

[erquhart]

This should be resolved when #1407 is resolved. Leaving open until then.

Specifying a false default as in - {label: "Noindex", name: "no_index", widget: "boolean", default: false} does not work for me. I am still forced to click twice on the toggle to make it falsy.

@erquhart Any update on this? I'm having the same problem that @belmarca has.

Hi @miguelt1, the best way to move this issue forward is to submit a contribution for it
