Transition form not working on multilingual website

I've tested this on a clean site having added a new language, switching both the user language and the site default language, and can't reproduce the issue. This may have been resolved since the issue was posted. If not please let me know.

Hello,
We still have the problem, it's not solved yet.

Can you please provide more detail so we can reproduce it? Possibly include screenshots and the webform source YAML if you can. I have done what you have described in the initial issue, with English and French, and it has not had an issue.

Could you please try it in the Arabic language? which is right to left language.

Hello,
I have the same issue. I have a multilangual site with a webform. In the base language the webform field works fine, but when I translate the form the webform the element disappears.

Steps to reproduce:

1. Create an empty Drupal 9
2. Install webform_workflows_element and the dependencies
3. Enable multilingual and a secound language
4. Create a workflow and translate it
5. Create a webform with the webform_workflows_element element and link the previously created workflow
6. Create a translation for the webform
7. Create a submission in each language

After these steps in the original language the init state value will be set in the result page, but the translation stays blank.

I have took a quick look and it seams that when on another language $webform->getElementsOriginalDecoded() will return only translations in the elements array, and the condition for finding workflow_element will never work.

Part where elements are gathered:

public function getWorkflowElementsForWebform(WebformInterface $webform): array {
    $elements = $webform->getElementsOriginalDecoded();
    return $this->filterWorkflowElements($elements);
  }

protected function filterWorkflowElements(array $elements): array {
    $filtered = [];
    foreach (Element::children($elements) as $key) {
      $element = $elements[$key];
      if (isset($element['#type']) && $element['#type'] == 'webform_workflows_element') {
        $filtered[$key] = $element;
      }
      $filtered += $this->filterWorkflowElements($element);
    }
    return $filtered;
  }

I am not sure if this has additional implications, but if using $webform->getElementsDecoded() instead of $webform->getElementsOriginalDecoded() I get full element structure, so further conditions are working properly.

after the patch install, i get the site error

Here is my version for this issue, works for me

Hmm, so big diff between 1.0.x and 1.0.0 alpha3, this is why cannot apply the patch.

works for 1.0.0-alpha3
