assigning ownership of an actor who picks new task

Q&A
1

We have the following challenge to overcome: An actor A initiates task filling a Form. The task appears as a New Task in the list of Tasks of range of actors together, let’s say B, C and D. Whoever will pick the Task (by clicking an Accept button) will become owner of it. How to assign all subsequent activities (approvals, rejects, history logs etc.) to the actor who picked the task and became owner?

We use Bonita 6.1.

When the user (B, C, or D) executes the task, you can store his ID in a process variable. In the subsequent tasks, you can use the actor filter "single user" using the process variable with the ID as parameter.
