com.google.gwt.event.shared.ummbrella异常：捕获异常：（TypeError）@org.moxieapps.gwt.highcharts.client.BaseChart:：nativeRenderChart

我正在尝试将“图表”（HighCharts角规）添加到流程面板。 添加时，我得到以下异常

我添加了导入，如highcharts.js、highcharts-more.js和exporting.js 在我的GWT.html中

但它还是给出了一个例外。 请帮忙

嗨，伊格纳西奥

谢谢你的回复。 我已经对它进行了调试，在highcharts提供的BaseChart类中，我找到了b，它是布尔值

这是导致BaseChart类中异常的行

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()
        );

从

并添加了以下内容 窗玻璃 YAxis（勾选位置、宽度、颜色） GaugePlot选项（颜色、线宽、堆叠）， 系列（点）， 工具提示（ValueSuffix）

我正在安排一切。 我验证了设置为“nativeRenderChart”方法的所有14个对象都不为空

仍然得到相同的异常！！！！ 一点线索也没有：（！！！

请帮助我..

这是与JS等效的NullPointerException。您可能错过了一些图表配置，结果失败。要准确了解发生了什么，建议的策略是调试您的项目（代码服务器）并使用chrome开发工具“捕获异常时暂停”。这将完全停止在此NPE，您应该看到缺少的内容以及

b

的含义。您必须查看chrome中的所有源代码；Java、JSNI或依赖的JS libs。

我已解决此问题。 问题在于以下代码

GaugePlotOptions plotOptions = new GaugePlotOptions();
//  plotOptions.setStacking( Stacking.NORMAL ); <<--- CULPRIT

GaugePlotOptions plotOptions=新的GaugePlotOptions（）；
//plotOptions.setStacking（Stacking.NORMAL）；谢谢，seriesLabelFormatters.getJavaScriptObject（）返回为false，b几乎是布尔值。我上面提到的所有设置都是布尔值，是否有我没有设置的必填字段？
