[英]GWT Application does not work in IE
I have a web app developed with GWT. 我有一个用GWT开发的Web应用程序。 In any browser except IE everything works fine.
在除IE之外的任何浏览器中,一切正常。 In IE 7, 8 or 9 it breaks.
在IE 7、8或9中会中断。
The link is https://dev.sertal.net/SertalVision/?locale=de#LoginPlace:test:sertal.ch 链接为https://dev.sertal.net/SertalVision/?locale=de#LoginPlace:test:sertal.ch
In any Browser, the username is filled with test and the tenant with sertal.ch 在任何浏览器中,用户名都填充了test,而租户则填充了sertal.ch
The solution I found is to tell people to install ChromeFrame, but one reason I chose GWT was for its browser portability. 我发现的解决方案是告诉人们安装ChromeFrame,但是我选择GWT的原因之一是其浏览器的可移植性。
The error message in IE is: IE中的错误消息是:

IE can not handle NullPointerExceptions as well as others. IE无法像其他人一样处理NullPointerExceptions。 I corrected the NullPointer and now it works.
我更正了NullPointer,现在它可以工作了。
Setting the GWT output style to DETAILED allowed me to identify what was wrong. 将GWT输出样式设置为Detailed使我能够确定出什么问题了。
