Placeholder from form (user_picker) is not resolved in workflow

Discussion/Misc

Hi everyone,

I have an issue with user assignment in a BlueSpice workflow where a value from a form (user_picker) should be set as the assignee for a task.

What I’m doing:

  • In the first step of the workflow (“Collect Data”), a form with a user_picker field (e.g., “FachlicherPrüfer”) is filled out.

  • In a following user task (“Fachliche Prüfung”), I set the assigned_user property to the placeholder {{{Activity_077wv6l.FachlicherPrüfer}}}.

The problem:

  • The placeholder is not replaced by the actual username, but is taken literally as “Activity_077wv6l.FachlicherPrüfer”.

  • As a result, the task is not assigned to a real user.

What I have checked:

  • The field name in the form and the placeholder match exactly.

  • The Collect Data step is set as the initializer.

  • If I enter a fixed username, the assignment works.

  • I have tested both placeholder variants:

    • {{{Activity_077wv6l.FachlicherPrüfer}}}

    • {{{Activity_077wv6l.FachlicherPrüfer.0}}} (in case the value is stored as an array)

Question:
Does anyone have an idea why the placeholder is not being resolved? Are there any known bugs or special requirements for passing user_picker values in workflows?
Any help is appreciated!

Best regards,

Torben
