This happens when you try to set a state in an element that is already
changing its state.
For example:
MouseArea {
id: area
width: 100
height: 100
states: State {
when: area.pressed
PropertyChanges { target: area; state: ""; }
}
}
Probably in your case a state triggered other states and while these
states are being changed another state in the chain is trying to
change one of them.
