ListView {
model: someValidModel
currentIndex: 4
}

annoyingly, you are right :p
this actually works, the problem was that i was loading the model too late, after componentComplete.

now, loading the model in the ctor and just relying on one single binding for currentIndex works perfectly.

note: i removed onCurrentIndexChanged: positionViewAtIndex as i want to put it on the gridview kcm component itself, as i think it belongs there.
