IE9 - in Document mode IE9 standards, CKEditor does not run

[Krzysztof Studnik]

IE9 v 9.0.8080.16413

• fresh install of IE9, cache cleared
• go to nightly builds and select any sample

Result:
CKEditor does not load into text areas. If it loads Open console (IE developer tools):

• set browser mode to IE9
• set Document mode to IE9 standards

Result, a JS error in console (in Nightly):

SCRIPT1004: Expected ';' 
ckeditor.js, line 14 character 238
SCRIPT5009: 'CKEDITOR' is undefined 
ui_languages.html, line 98 character 6

The {{{SCRIPT1004}} part, occurs in all CKEditor versions

It seems to be a problem with the javascript compression, and it also affects CKFinder.

Caused by mandatory semi-colon required for do...while in IE9, I'd say it a bug instead of an improvement, as old school way (optional semi-colon) introduce no ambiguousness at all.

Fixed with [6424:6425].

FYI - It looks like IE9 has fixed this in their latest GA version.

I'm still experiencing this bug in CkEditor version 3.6.4

My site is forced to implement Document Mode: IE 9 Standards by adding:

<meta http-equiv="X-UA-Compatible" content="IE=9.0">

The current demo loaded in [www.ckeditor.com/demo] is in IE 7 Standards Mode. When you change that to IE 9 Standards by pressing F12 in IE, it will still work though.

But if you start the site in IE 9 Standards by implementing the above code, the editor will not show, only the toolbar.

The demo at www.ckeditor.com/demo runs in IE 9 standards mode by default, and it works fine here.

If you're "forced to implement Document Mode: IE 9 Standards", that might mean that your site has other problems because by default IE 9 tries to use the best standards mode.

That is not true. IE9 runs in IE9 mode by default and trust me there is no problem with default implementation. I would rather look for problems on your page or web app.
