Qml ListView full page smooth transition

[Illogica]

Hello,
I'm trying to implement a paged viewer using ListView, but I'm not able to implement transitions between the pages.
Here's an example qml file:

import QtQuick 2.0
import QtQuick.Controls 1.4

Rectangle {
    id: root
    height: 150; width: 300

    ListView{
        id: listView
        anchors.fill: parent
        model: listModel
        delegate: listDelegate
        orientation: ListView.Horizontal
        snapMode: ListView.SnapToItem
        highlightMoveDuration: 150

        function updatePosition(){
            //positionViewAtIndex(currentIndex);
            //positionViewAtIndex(currentIndex, ListView.Beginning);
            positionViewAtIndex(currentIndex, ListView.Center);
            //positionViewAtIndex(currentIndex, ListView.End);
            //positionViewAtIndex(currentIndex, ListView.Visible);
            //positionViewAtIndex(currentIndex, ListView.Contain);
            //positionViewAtIndex(currentIndex, ListView.SnapPosition);
        }
    }

    ListModel{
        id: listModel
        ListElement{ info: "Page1"; colorString:"blue"}
        ListElement{ info: "Page2"; colorString:"red" }
        ListElement{ info: "Page3"; colorString:"grey" }
        ListElement{ info: "Page4"; colorString:"green" }
        ListElement{ info: "Page5"; colorString:"orange" }
    }

    Component{
        id: listDelegate

        Rectangle{
            height: root.height
            width: root.width
            color: Qt.lighter(colorString)
            Text{
                id: text
                anchors.centerIn: parent
                text: info
                color: Qt.darker(colorString)
            }
        }
    }

    Button{
        id: buttonNext
        anchors.right: parent.right
        anchors.verticalCenter: parent.verticalCenter
        text: "Next Page ->"
        onClicked: {
            if(listView.currentIndex<listModel.count-1){
                listView.currentIndex++;
                listView.updatePosition();
            }
        }
    }

    Button{
        id: buttonPrevious
        anchors.left: parent.left
        anchors.verticalCenter: parent.verticalCenter
        text: "<- Previous page"
        onClicked: {
            if(listView.currentIndex>0){
                listView.currentIndex--;
                listView.updatePosition();
            }
        }
    }
}

My biggest problem is the updatePosition() function. If I don't pass a second parameter, calling just positionViewAtIndex(currentIndex) i get a nasty "Error: Insufficient arguments", but I have a smooth transition between the pages. If pass any kind of second parameter the page transition is lost.
I'm seriously considering shipping my application with that nasty error...
Am I missing something? How can I achieve smooth transition between the pages?

Best regards,
Loris
