The concept here is that once an animation is part of a larger group, it is
the group that decides when it's the right moment for each of its children
to start or stop. That restriction is tied to the concept of AnimationGroup.

I was aware of that because I'm used to the similar C++ API, but I don't
know whether that's documented in QML. Maybe it deserves some more detail on
that.

I couldn't find where you are starting the animation but since the
ParallelAnimation does not have an id, and the Rotation animation has, I'm
assuming you might be calling "rot.start()" somewhere... or "rot.enabled =
true".

BTW, I'm online at #qt-labs @ Freenode if you wanna talk with less overhead
