Select other computed token error

Please provide the yaml of a minimal form that exhibits the bug.

Thanks cilefen

Creating a simple multi-paged test form with select other element didn't give errors, but adding a conditional visibility to the select other element did. So it seems to be related to have conditions in the form.

The form I'm creating has lots of visibility/required conditions on elements, but not actually on the select other element.

first_page:
  '#type': wizard_page
  '#title': 'First page'
  standard_select_question:
    '#type': select
    '#title': 'Standard select question'
    '#options': yes_no
    '#required': true
second_page:
  '#type': wizard_page
  '#title': 'Second page'
  do_you_want_to_answer_the_next_question:
    '#type': select
    '#title': 'Do you want to answer the next question'
    '#options': yes_no
  select_with_other_question:
    '#type': select_other
    '#title': 'Select with other question'
    '#options': yes_no
    '#other__option_label': Other
    '#other__placeholder': 'Please enter the preferred pronoun'
    '#states':
      visible:
        ':input[name="do_you_want_to_answer_the_next_question"]':
          value: 'Yes'
third_page:
  '#type': wizard_page
  '#title': 'Third page'
  computed_tokens:
    '#type': computed_token
    '#title': 'Computed tokens'
    '#mode': text
    '#template': '"[webform_submission:values:standard_select_question]","[webform_submission:values:do_you_want_to_answer_the_next_question]","[webform_submission:values:select_with_other_question]"'
    '#store': true

Further information - if rendering token as raw value [webform_submission:values:select_with_other_question:raw]

Get two errors showing on form:
User error: "select" is an invalid render array key in Drupal\Core\Render\Element::children() (line 98 of core\lib\Drupal\Core\Render\Element.php).

User error: "other" is an invalid render array key in Drupal\Core\Render\Element::children() (line 98 of core\lib\Drupal\Core\Render\Element.php).

Both regarding the token [webform_submission:values:select_with_other_question:raw]

_webform_token_get_submission_value('select_with_other_question:raw', Array, Object, Object, Object) (Line: 743)
webform_tokens('webform_submission', Array, Array, Array, Object)

I ran into this issue too. Doing some debugging with XDebug, it seems the error is coming from Drupal\webform\Plugin\WebformElement\OptionsBase::formatTextItem/formatHtmlItem. The call to getValue is returning an array of ["select" => [...], "other" => "..."] for some reason, but only when called from inside a computed token/computed twig field and when the select element is conditionally visible.

When the select element isn't conditional/when the token is in the confirmation page, it seems to be returning a string (either the option selected, or the value of the Other field), as expected.

I was able to do an ugly workaround by using a computed twig field, by detecting if it's an array and returning an empty string, otherwise computing the token:

{{ data.select_element is iterable ? '' : webform_token('[webform_submission:values:select_element]', webform_submission) }}

The attached webform replicates the issue using the elements from #3.

@jrockowitz Thanks for the repro config.

I've submitted an MR with tests that fixes this issue. Interestingly, there was already code to handle a similar bug in OptionsBase::getElementSelectorInputValue, from issue #3000202 → . I pulled that code out to an overriden getValue function which should fix the bug for all code paths including OptionsBase::formatTextItem/formatHtmlItem mentioned above, which is the source of the error in this issue.

We've now been using the fix in MR #469 in production for a month without any errors, and have been able to remove our workarounds. It'd be great if someone else could test and change this issue to RTBC!

Tested today, works on a clean install & ran "test-only changes" job, which shows coverage. Everything looks fine by me !
I'll change it to RTBC shortly if no one else does in the meantime.
