Getting Exception while adding Angular Gauge Chart to Flow Panel

[KARTIKEYAN]

I am trying to add a 'Chart' (HighCharts-Angular Gauge) to a Flow Panel. While adding I getting the below exception

com.google.gwt.event.shared.UmbrellaException: Exception caught: (TypeError) @org.moxieapps.gwt.highcharts.client.BaseChart::nativeRenderChart(Ljava/lang/String;Lcom/google/gwt/core/client/JavaScriptObject;ZZLcom/google/gwt/core/client/JavaScriptObject;Lcom/google/gwt/core/client/JavaScriptObject;Lcom/google/gwt/core/client/JavaScriptObject;Lcom/google/gwt/core/client/JavaScriptObject;Lcom/google/gwt/core/client/JavaScriptObject;Lcom/google/gwt/core/client/JavaScriptObject;Lcom/google/gwt/core/client/JavaScriptObject;Lcom/google/gwt/core/client/JavaScriptObject;Lcom/google/gwt/core/client/JavaScriptObject;Lcom/google/gwt/core/client/JavaScriptObject;)([string: 'Chart', JavaScript object(15907), bool: false, bool: false, JavaScript object(15932), JavaScript object(15933), JavaScript object(15934), JavaScript object(15924), JavaScript object(15928), JavaScript object(15923), JavaScript object(15926), JavaScript object(15927), JavaScript object(15930), JavaScript object(15931)]):

I have added imports like highcharts.js , highcharts-more.js and exporting.js in my GWT.html

But still it is giving an exception.
I have searched for this exception and no one has answered.
People get exception stating 'HighCharts' is undefined,
But I am getting as
'b is undefined'

When I debugged it,
In the BaseChart class provided by highcharts I found the b, which is boolean

This is the line where it is causing the exception in BaseChart class,

chart = nativeRenderChart(
getChartTypeName(),
createNativeOptions(),
toolTip != null && toolTip.getToolTipFormatter() != null,
legend != null && legend.getLabelsFormatter() != null,
chartEventHandlers.getJavaScriptObject(),
seriesEventHandlers.getJavaScriptObject(),
pointEventHandlers.getJavaScriptObject(),
xAxisEventHandlers.getJavaScriptObject(),
yAxisEventHandlers.getJavaScriptObject(),
xAxisLabelFormatters.getJavaScriptObject(),
yAxisLabelFormatters.getJavaScriptObject(),
yAxisStackLabelFormatters.getJavaScriptObject(),
plotOptionsLabelFormatters.getJavaScriptObject(),
seriesLabelFormatters.getJavaScriptObject()
);

Took a javascript from http://jsfiddle.net/highcharts/EjRLw/

and added the following Pane, YAxis (tick postion,width,color) GaugePlotOptions(color,linewidth,stacking), Series(Points), ToolTip(ValueSuffix)

I am setting Everything. I verified all 14 objects set to 'nativeRenderChart' method are not null.
Still getting same exception!!!! No clue at all :( !!! Please help me..

Please help!!!

I have resolved this. The issue was with the below code,

GaugePlotOptions plotOptions = new GaugePlotOptions();
// plotOptions.setStacking( Stacking.NORMAL ); <<--- CULPRIT
Set 'Stacking' in 'GaugePlotOptions' was causing the exception. Once it is removed Chart appeared in the panel.
