No field type after module enabling.

It's working proper at my side and i can see "Color" field. Please clear drupal cache or install module once again and check.

I can confirm it.
The module doesn't work with Drupal 8.2.1

The module is far from being compatible with 8.2 :( see https://www.drupal.org/docs/8/creating-custom-modules/create-a-custom-fi...

Not at all.
I have used the version 8.x-2.x-dev of the module today and it works fine.
At the time to write this message the module is still working without errors.
I will report problems if they come.

Yes you are right. I installed color_field with composer and used "@dev" as version constraint. Thats why my module versions was in fact very old. Now with

composer require drupal/color_field "2.x-dev"

It works like a charm on Drupal 8.2

Same problem with Drupal 8.3.3. After upgrading to dev, now I can add fields of type `Color`.

Same issue for me :( in Drupal 8.3.5
The dev version worked:

composer require drupal/color_field "2.x-dev"

thanks @zuernBernhard

Maybe it's about time for a new release of this module so people don't have to depend on dev versions?

There's no patch here. Back to active.

Please read the thread @heddn.

The problem has already been fixed in the latest dev, but the fix is not part of the current "stable" 8.x-2.x version. This means that the latest stable version is completely broken and a new stable version needs to be tagged to fix that.

Composer pulls nearly the same code for 2.x-dev and 2.0@rc when I try, both of which haven't been updated since April and don't show any field types for me. When I diff them, the only changes are meta information injected by Drupal.org.

This is confirmed on the project page which indicates the RC was released more recently than the most recent commit on the commits page, which was from April.

Is there newer code somewhere that I'm just not seeing, or is the cause of my issue perhaps different than this one?

Scratch that, had a problem with cache clearing not working, the field type works fine for me now.

However, since the code in the current RC matches the code on dev, and has for ~5 months, are people still running into an issue with the RC version, or can this be marked fixed?

Seeing the same problem ...

The color field is not showing in the add field selection dropdown.
Clear cache, restarted browser, but still no color field type available.

Same problem in two different site installations ...

Confirm dev works but RC2 does not

Dev === RC2 per commit/tag.
However, if my visual review is wrong, all that needs to happen is a new release made. So, I'm going to reach out to Tagoo and see if we can't get at least the RTBC tickets merged and a new release.

I'm marking this as fixed. If anyone gets it happening again with latest dev or a version released May 16th 2018 or later, please re-open.
