Question

我在Eclipse中遇到异常我正在尝试使用GWT插件创建Web应用程序项目。我创建了一个复合（名称：浏览器）。之后，我尝试使用Choose Component选项在类（name：Home_Page）中添加浏览器组合。

当我添加它时，在设计视图中给出错误：

创建浏览器时出现异常。有关详细信息，请参阅错误日志。

请帮我纠正这个问题。

Answer 1

Stack overflow errors（堆栈跟踪中的第一行）没有太多原因。最可能的情况是，当你添加复合时，你以某种方式进行无限递归（也就是说，一个调用自身的方法，它调用自身，调用自身，调用自身......）。

查看您正在使用的规格，并确保正确添加复合材料。它可能只是某个地方的错字，但听起来问题就是接近插入点。
