Eclipse error constantly pops up while editing Javascript
提问by BishopZ
I am working on relatively small (100-300 lines) Javascript files in Eclipse and periodically it gets really upset about some piece of code and pops up this error every time I place the cursor on that line. The error is:
我正在 Eclipse 中处理相对较小（100-300 行）的 Javascript 文件，并且每次我将光标放在该行上时，它都会对某些代码感到非常不安，并弹出此错误。错误是：
'Requesting JavaScript AST from Selection' has encountered a problem.
An internal error occured during "Requesting JavaScript AST from selection".
java.lang.NullPointerException
While I am converting this:
当我转换这个时：
if(p){
// enter code here
} else { return false; }
into this:
进入这个：
if(p){
// enter code here
} return false;
the error pops up several times. Each time it stops my typing and requires me to click the okay button. I then type two more characters and the error appears again.
错误弹出几次。每次它停止我的打字并要求我单击“确定”按钮时。然后我再输入两个字符，错误再次出现。
Any ideas how to either prevent the error or disable whatever Javascript AST is?
任何想法如何防止错误或禁用任何 Javascript AST？
This is on Eclipse Java EE, Indigo Service Release 2. It is almost a flat install, only two plugins installed and neither are for SVN and have nothing to do with Javascript.
这是在 Eclipse Java EE，Indigo Service Release 2 上。它几乎是一个平面安装，只安装了两个插件，而且都不是针对 SVN 的，也与 Javascript 无关。

At first I thought this was just a trick, but it is working so well, I had to post it as an actual answer.
起初我以为这只是一个技巧，但效果很好，我不得不将其作为实际答案发布。
When the error window pops up, don't close it. Just drag it off to the side, focus back on the main window and keep editing.
当错误窗口弹出时，不要关闭它。只需将其拖到一边，重新关注主窗口并继续编辑。
When the error happens again Eclipse doesn't change the focus back to the error message. Focus stays in the editing window and you can continue to edit the document.
当错误再次发生时，Eclipse 不会将焦点更改回错误消息。焦点停留在编辑窗口中，您可以继续编辑文档。

An even better answer (from the bug report linked by Cliff Ribaudo, comment #10 and others):
一个更好的答案（来自 Cliff Ribaudo 链接的错误报告，评论 #10 和其他人）：
Turn off Toggle Mark Occurrences (Alt-Shift-O or the paintbrush icon on the toolbar, which handily, will show you your current state).
关闭 Toggle Mark Occurrences（Alt-Shift-O 或工具栏上的画笔图标，可以方便地显示您的当前状态）。
Thanks Cliff!
谢谢悬崖！
