Special Characters Window causes CKEditor to never open again.

[onepoint]

Clicking the Omega (Special Characters) symbol, (​http://screencast.com/t/LzmUDUbfl), selecting a character, and then clicking Ok, only to reopening CKEditor causes it never load properly (​http://screencast.com/t/z4RGIXE5Bzm)

Chrome spits on an error:

Uncaught TypeError: Object #<Object> has no method 'indexOf' : ckeditor.js:9

Were you able to reproduce the bug in CKEditor demo pages - ​http://ckeditor.com/apps/ckeditor/3.5.2/_samples/index.html (the last stable version) or in nightly build version - ​http://nightly.ckeditor.com/demo ? If you are able to reproduce it, could you please provide us with a step by step scenario?

I see that you are using CKEditor in your web application. Perhaps it's not the problem of CKEditor itself but your application settings?

Yes.

What we're doing is removing the instance of CKEditor, and then creating a new one. It is essentially the exact same as

​http://ckeditor.com/apps/ckeditor/3.5.2/_samples/ajax.html

What i did was, Create Editor, click the Omega Symbol, add anything (Example: Exclamation Point), Remove Editor, and then click Create Editor again, but only this time the same error spits out:

Uncaught TypeError: Object #<Object> has no method 'indexOf'

[Jakub Ś]

Sorry I've missed something that obvious.

The error occurs in file ckeditor/_source/core/tools.js in line 522 Log from FireBug : array.indexOf is not a function - return array.indexOf( entry );

The error has started occurring since CKEditor version 3.5.

Is there a current work around in place?
