Ok, now I know that I have to do a call: on the task. This not how
my logic works. It would expect the task to just return and the
following statements set up new components to show.

In general I would expect the task to end. I understand a task as
"do these things and then you are finished so exit". The place
where the task was could be nil then and it would displayed nothing
(as long as this would work). In my case I just set up components
in the background which will show automatically as soon as the task
exits.
Or I would expect to work like normal WAComponents. If I'm not wrong
they render themselves as long as no answer is called. But if it is
called they return. So this could also be true for a WATask.
