An internal error occurred during: "Requesting JavaScript AST from selection"
提问by Swatantra Kumar
I'm facing unique error/alert-popup while editing JavaScript files in Eclipse and it pops up this error every time I place the cursor on that line.
在 Eclipse 中编辑 JavaScript 文件时，我遇到了独特的错误/警报弹出窗口，每次我将光标放在该行上时，它都会弹出此错误。
JS: NullPointerException when cursor is placed at the end of the line containing return statement.
JS: NullPointerException 当光标放在包含 return 语句的行的末尾时。
foo.bar = function(x) {
if (xyz) {
return fn(x);?error?
}
return fn(x);?error?
return (fn(x));?error?
return new fn(x);?ok?
return x;?sometimes?
return "";?error?
return x+"x";?error?
return this.x;?error?
return fn(
x);?error?
return new fn(
x);?ok?
return;?error?
};
- ?? — cursor position
- ?ok? — no error
- ?error? — triggers error
- ?sometimes? — I have code that never triggers an exception in that case, but I don't see a pattern.
- ?? — 光标位置
- ？好的？— 没有错误
- ？错误？— 触发错误
- ？有时？— 在这种情况下，我的代码永远不会触发异常，但我没有看到模式。
If cursor is at the end of the line of a return, this exception happens:
如果光标位于返回行的末尾，则会发生此异常：
An internal error occurred during: "Requesting JavaScript AST from selection".
java.lang.NullPointerException
The Eclipse error is:
Eclipse 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
Is there a solution or workaround available to fix the problem?
是否有解决方案或解决方法可以解决该问题？

Simplest solution:
最简单的解决方案：
Turn off Toggle Mark Occurrences (Alt-Shift-Oor the paintbrush icon on the toolbar, which handily, will show you your current state).
- It's just disabling the feature of highlighting other occurrences of whatever variable, etc you have your cursor on.
关闭 Toggle Mark Occurrences（Alt- Shift-O或工具栏上的画笔图标，它会方便地显示您的当前状态）。
- 它只是禁用突出显示任何变量的其他出现的功能，等等你有你的光标。

Opening JavaScript files in text editor helps. You may like to change the default default file association for js files to Text Editor.
在文本编辑器中打开 JavaScript 文件会有所帮助。您可能希望将 js 文件的默认默认文件关联更改为文本编辑器。
