com.google.gwt.event.shared.UmbrellaException：捕获到异常：（类型错误）@ org.moxieapps.gwt.highcharts.client.BaseChart :: nativeRenderChart

Question

我想一个“图表”（HighCharts - 角计）添加到流面板。同时加入我得到下面的异常

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)]):

        .
        .

我在GWT.html增加进口像highcharts.js，highcharts-more.js和exporting.js

但它毕竟是给一个例外。请帮忙。

还有伊格纳西奥，

谢谢回复。我已经调试它，在通过highcharts提供的BaseChart I类中发现的B，其是布尔

这是它造成的例外BaseChart班线，

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()
        );

拿了一个javascript从http://jsfiddle.net/highcharts/EjRLw/

并增加了以下窗格，Y轴（蜱现在的位置，宽度，颜色）GaugePlotOptions（颜色，线宽，堆叠），系列（点），工具提示（ValueSuffix）

我设置的一切。我验证设置为“nativeRenderChart”方法的所有14个对象不为空。

仍然得到同样的异常!!!!不知道在所有:( !!!请帮助我..

Answer 1

这是NullPointerException异常等值JS。你可能会错过一些图表配置，并最终失败。要了解到底发生了什么建议的策略是调试项目（代码服务器），并使用Chrome浏览器开发工具“上捕获的异常暂停”。这将在这个NPE正好停下来，你应该看到的是缺失的，什么意思b。您必须在Chrome中看到所有源代码; Java中，JSNI或依赖JS库。

Answer 2

我已经解决了这一点。这个问题是与下面的代码，

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

坐落在“GaugePlotOptions”堆积'导致异常。一旦它被删除图表出现在面板上。
