问题描述

I am new to GWT and my program was compiling fine until now when I am trying to add a calendar with round corners using rico.js.我是 GWT 的新手，当我尝试使用 rico.js 添加带圆角的日历时，我的程序一直在编译。 What doest this error mean and what should I be looking for?这个错误是什么意思，我应该寻找什么？

This is also happening ONLY IN FIREFOX (I have 4.0.1)这也仅在 FIREFOX 中发生（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?

Thank you谢谢

Is the external package rico.js wrapped in gwt or is it just plain js?外部 package rico.js 是包裹在 gwt 中还是只是普通的 js？ If its a wrapper, see if you have included the module in your.gwt.xml file.如果它是包装器，请查看您是否已将模块包含在您的.gwt.xml 文件中。 If its plain js, see if you have added the script tag in the html file.如果是纯js，看你是否在html文件中添加了script标签。 If neither, then we will need to see the code如果两者都不是，那么我们将需要查看代码
