QML: QtCharts 2.0 “Invalid grouped property access”

fhdns

I have this code:

        import QtQuick 2.0
        import QtCharts 2.0
        ...
        ChartView {
            id: testChart
            title: "Chart"
            width: parent.width
            height: parent.height / 3
            legend.visible: true
            legend.alignment: Qt.AlignRight
            legend.font.pixelSize: ScreenModel.dp(10)
            legend.font.bold: true
            antialiasing: true
            ...
        }

If I run this code on ipone simulator, it works fine, but when I run on really Iphone 4S, it crashes with log:

where TestPage.qml:727 is legend.visible
Why this code works in simulator and doen's work on really device?

Hi,

QtCharts is a commercial package, you should rather contact the Qt Company through your Qt Account Support Center link.
