DeviceInfo.startBatteryLevelChanged() not functioning as spesified in SystemInfo 1.1 QML Plug-in documentation

DeviceInfo element behaves like in Mobility 1.2 although 1.1 plug-in imported. See code below:

---

import QtQuick 1.0
import com.nokia.symbian 1.0
import QtMobility.systeminfo 1.1

Page {
id: mainPage

DeviceInfo {
id: deviceinfo

Component.onCompleted:

{ // below doesn't work with although it should work with QtMobility.SystemInfo 1.1? // deviceinfo.startBatteryLevelChanged(); // this works, although it shouldn't as it's the new property added in QtMobility 1.2 deviceinfo.monitorBatteryLevelChanges = true }

onBatteryLevelChanged:

{ progressbar1.value = batteryLevel }

}
