Question

我是GWT的新手，我的程序编译正常，直到现在我正在尝试使用rico.js添加圆角日历。这个错误意味着什么，我应该寻找什么？

这也只发生在FIREFOX（我有4.0.1）

[ERROR] Line 105: No source code is available for type com.packtpub.gwtbook.widgets.util.Rico; did you forget to inherit a required module?

谢谢

这里也是跟踪

Answer 1

外部包rico.js是用gwt包装还是只是简单的js？如果是包装器，请查看是否已将该模块包含在.gwt.xml文件中。如果是普通的js，看看你是否在html文件中添加了脚本标签。如果两者都没有，那么我们需要看代码

新的GWT需要帮助解决错误
