Thanks, I tried that. Unfortunately, it seems as if the "running"
property of the AnchorAnimation object isn't changed when used in a
state transition. The way I test this is by implementing a
"onRunningChanged" slot on the object and using console.log() - I
don't get any output, and the trick you suggested with the opacity
doesn't work for that reason (otherwise it would be great and really
compact).

Is that a bug in QML (should an Animation inside a Transition have its
"running" property set to true while it's running due to a state
change?) or is this on purpose. If so, is there any other way to
achieve this "special case while in transition" mode?

Thanks,
Thomas
