In previous versions of Tasklist, the form was reloaded when metadata changed. With CAM-9856, the Form always stays loaded.

I want to react to metadata changes from Tasklist, such as setting the assignee. If the Form relies on assignee data to customize it's view, I can refresh the view if I am notified.

Implementation
Let's add a new event listener here: https://docs.camunda.org/manual/7.12/reference/embedded-forms/lifecycle/

TBD: Do we want a general 'metadata-changed' listener with the changed metadata as payload or fine-grainer (assignee-changed, duedate-changed, ...) listeners?

AT

• I can register a hook in an embedded form that is called when metaData changes occur in Tasklist
