"PWC3999:响应已提交后无法创建会话" [英] "PWC3999: Cannot create a session after the response has been committed"

问题描述

我的应用程序页面之一出现这个奇怪的问题.它引发了我在标题上提到的错误:

I'm having this weird problem with one of the pages of my application. It's throwing the error I mention on the title:

PWC3999: Cannot create a session after the response has been committed

我已经检查了与此主题相关的其他帖子，但没有看到任何适用于这种情况的信息，因为没有向应用程序添加新的Servlet/Filter，并且在对javascript的javascript进行了一些细微更改之后，错误才刚刚开始xhtml文件. 如果我删除任何行，错误就会停止显示. 起初，我认为缓冲区大小可能会有些问题，并增加了值(只是确定要大10倍)，但这并没有解决问题.

I've checked other posts regarding this subject, but I don't see anything that applies to this situation, because no new Servlet/Filter was added to the application and the error just started after some minor changes on the javascript of the xhtml file. If I delete any line the error stops showing. At first I believed that it could be some problem with the buffer size and increased the values (10x bigger, just to make sure), but that didn't solved the problem.

而且，老实说，我认为这与文件的大小无关，因为它曾经更大并且可以正常工作.

And, to be honest, I don't think this is related to the size of the file, because it used to be bigger and it worked without any problems.

我还检查了这种情况，找不到任何转发/重定向.

I also checked and couldn't find any forward/redirect being called for this case.

有人可以帮我吗?

亲切的问候，

此错误在GF v3.1上发生，但在GF v3.0.1上没有发生，这可能是facelets实现的错误吗?

推荐答案

我遇到了同样的问题，当我添加一个没有id的额外按钮时，异常出现在日志中，但是当我将id添加到新按钮中时，异常消失.尝试将ID放到产生错误的组件上.

I had the same problem, when I add an extra button without id that exception appear in the log, but when I add the id to the new button the exception disappear. Try putting the id's to the components wich generate the error.
