'Statement Expected' Syntax Error Highlighting on First Line of JS File in PHPStorm

Question

I have a JS file where no matter what is put on the first line (comment or code), PHPStorm lists a syntax error. When I hover over the error, the description says "Statement Expected". What it looks like:

enter image description here

Is this a bug with the IDE or something that can be disabled?

EDIT

Sample file here

Please upload that file somewhere (yes, actual file, not just contents on its own) and share the link. But before that: 1) create another file anywhere in your project and copy-paste from this one -- see if error will remain there as well. if not -- compare file lengths. 2) Try "File | Invalidate Caches.." -- maybe some internal index corruption (sometimes happens for PHP files) — LazyOne

@LazyOne I created another file and the same error highlight appears. Tried the 'File' -> 'Invalidate Caches' route and still the same problem. I added a link to the sample file in the question — Lloyd Banks

Seeing the same error on phpstorm 7.1.3. But the error goes away if you remove the leading space in front of var myApp. At second glance.. I don't think that's a space.. some other leading white-space character causing issues. — Mike B

You have UTF-8 BOM signature (EF BB BF) just before var myApp= line (first code line in that file)

If you remove it IDE will stop complaining.

P.S.
Yes -- IDE should be smarter in such case and should provide better error message and error location. Feel free to submit new ticket to the Issue Tracker at http://youtrack.jetbrains.com/issues/WI

This was good. I simply re-typed my function declaration, pasted the guts, and the issue went away. I agree JetBrains should be better at catching this one. I'll cross-post it over to their tracker.

@Imperative Please try "Zero Width Characters locator" plugin -- it has separate inspection and can detect such case (work OK with a file from your example).

Good to know. I linked this out of the issue but I'll mention this to them anyway. That makes it even easier to implement a fix.

In most of the cases this issue occurs due to copy paste. There may be some characters/line feed which may need to rewrite in your IDE.

In such cases simply copy your code to notepad and again copy it back to your IDE.

You can turn off "Properties > Languages & Frameworks > Template Data Languages" and error "statement expected" will go out.

Because this syntax is not correct for setted template. In my example, in the project i use php and angularjs, but phpstorm does not make defferences between them.
