When using a Date List field in a Webform. I refresh the form and receive the following error.

Warning: array_diff(): Argument #2 is not an array in Drupal\Core\Datetime\Element\Datelist::checkEmptyInputs() (line 357 of /vagrant/htdocs/core/lib/Drupal/Core/Datetime/Element/Datelist.php)

The following check that $input exists seems to do the trick. Any other suggestions?

What is $input in this case? Is it NULL like the title suggests? Probably need a small test to show this?

In the case of refreshing a webform, the value of $input being passed in is NULL. Which causes the subsequent calls using $input to fail. I will try to write the tests for this when I have some time, unless anyone else comes across the same issue.

I looked into adding some tests for this, but I was unable to reproduce the issue. Whenever I refreshed the form, $input was set to FALSE.

Thanks, on the basis of #5 this sounds like it is no longer occurring

It may be that webform has since changed.

@aeotrin are you able to provide steps to reproduce, starting from 'Install Drupal core'?

Thanks.

It is has been over a year and no steps to reproduce have been provided. Considering that this was not reproducible 4 years ago I think it is safe to close this now. Closing as outdated.

If you are experiencing this problem on a supported version of Drupal reopen the issue, by setting the status to 'Active', and provide complete steps to reproduce the issue (starting from "Install Drupal core").

Thanks!
