[Qt-qml] "Can't apply a state change as part of a state definition"

[mathias.malmqvist at nokia.com]

Hi, 

One of my state definitions triggers this error
<Unknown File>: QML StateGroup: Can't apply a state change as part of a state definition.
and I can't quite work out why. 

Is it the case that no part of the state definition (like a PropertyChange) may have *any* 
effect (direct or indirect) on a property that is part of a "when" expression determining 
what the current state is?


Cheers
Mathias
