Anyone knows why this ninjascript function that i have in AB tool bar buttons is not working when called from second tab, which is different wfrom which the indicator is on.

private void LineOnCloseFunc()
{
if (ChartBars.Properties.ChartStyleType == ChartStyleType.CandleStick)
{
ChartBars.Properties.ChartStyleType = ChartStyleType.LineOnClose;
}

else if (ChartBars.Properties.ChartStyleType == ChartStyleType.LineOnClose)
{
ChartBars.Properties.ChartStyleType = ChartStyleType.CandleStick;
}
chartWindow.ActiveChartControl.InvalidateVisual();
ForceRefresh();
}
