I'm attempting to build a webform (Webform 8.x, Drupal 8) that requires the ability for a user to submit the form multiple times.
To simplify the process for users, I'd like to set up some form fields to:
- be empty by on their first visit to the form
- for subsequent renders of the form, some form fields should be prepopulated with submissions from the previous submission
Is there a way to achieve this using tokens?
I'm attempting to use tokens to do this (details below) but various approaches aren't working.
All of the examples below address the first_name field, which is in the personal_information fieldset.
I have added the following tokens in the field's default value field with no luck:
- This support page about webform tokens (for webform 7.x): https://www.drupal.org/comment/reply/2790291 ...advises that I access the value using:
[submission:values:personal_information:first_name]
...but it doesn't work when I add it to the 'Default value' field. Instead, I receive an error from Drupal saying that:
Default value is using the following invalid tokens: [submission:values:personal_information:first_name].

If I follow the token guidance on the form in Webform 8.x, it seems to advise that I use this structure for my token:
[webform_submission:webform:element:first_name]
...the result is the field's label ('First name') is pre-populated in the field.
If I append the :clear suffix, the result is the same, the field's label is still pre-populated in the field.
This seems is the most successful option so far.

If I add :value to the token:
[webform_submission:webform:element:first_name:value]
...the result is the text of the token is pre-populated in the field.
If I append the :clear suffix:
[webform_submission:webform:element:first_name:value:clear]
...the field is empty on the first and subsequent submissions.
+++
If I use this, which seems to be the guidance in the token section about 'Webform tokens from submitted data':
[webform_submission:values:first_name]
...it renders the text of the token.
If I append the :clear suffix:
[webform_submission:values:first_name:clear]
...the field is empty on the first and subsequent submissions.
If I include the fieldset value:
[webform_submission:values:personal_information:first_name]
...the site returns an error message: "LogicException: The "[webform_submission:values:personal_information:first_name]" is being called recursively..." And a subsequent yaml error after changing it. The only way I can resolve this issue (even after editing the form's yaml via the CMS or the config file) is by deleting the form field and then re-creating it.

If I attempt this:
[webform_submission:values:first_name:raw]
...it renders the text of the token.
If I add the :clear suffix, the field is empty on the first and subsequent submissions.
