我想在GWT中使用PieChart.错误:没有可用的源代码

Question

在编译我的代码时,我遇到了这个问题:

No source code is available for type com.google.gwt.visualization.client.visualizations.corechart.PieChart; did you forget to inherit a required module?
 [ERROR] Line 30: No source code is available for type com.google.gwt.visualization.client.visualizations.corechart.PieChart.PieOptions; did you forget to inherit a required module?
 [ERROR] Line 38: No source code is available for type com.google.gwt.visualization.client.AbstractDataTable; did you forget to inherit a required module?
 [ERROR] Line 39: No source code is available for type com.google.gwt.visualization.client.DataTable; did you forget to inherit a required module?
 [ERROR] Line 40: No source code is available for type com.google.gwt.visualization.client.AbstractDataTable.ColumnType; did you forget to inherit a required module?
 [ERROR] An internal compiler exception occurred

我正在使用gwt 2.1和可视化.我尝试在*.gwt.xml中添加一个条目,但它没有帮助.任何帮助将受到高度赞赏.

你确定你已经添加了吗？

<inherits name='com.google.gwt.visualization.Visualization'/>

到您的*.gwt.xml文件？因为在我看来这是问题的原因.
