Uncaught exception: TypeError: 'win.getSelection' is not a function about codemirror-v1

window.getSelection is built into the browser. I'm not seeing this error. Which version of Opera are you using, and which CodeMirror page are you opening?

Oops, sorry.
I was actually trying to do this :
http://heydojo.co.cc/ckeditor-codemirror/index.html
and it is my fault. I am trying to do too much.

I use the latest snapshot of Opera Linux 10.70 from :
http://my.opera.com/desktopteam/blog/
(10.60 isn't as good.)

I think the problem I am having is that maybe I am trying to destroy and recreate a code mirror instance in a dirty way because in the demo linked above, I get two errors, one when the toggle toolbar button is clicked and the same when switching to and from source mode.

Uncaught exception: TypeError: 'b.getSelection' is not a function
Error thrown at line 12, column 946 in (b) in http://heydojo.co.cc/ckeditor-codemirror/ckeditor/plugins/codemirror/js/select.js:
var c=b.getSelection();
called from line 43, column 288 in () in http://heydojo.co.cc/ckeditor-codemirror/ckeditor/plugins/codemirror/js/editor.js:
select.markSelection(b.win);

So do you have any recommendations on how to destroy the CodeMirror instance cleanly straight after using the getCode() function?
I've read through the manual and it doesn't look like there is such a function.

Thanks,
Tony

Hi Tony,

I have pushed a fix to the CodeMirror git repository that should fix this. The problem was that a timeout was firing (for the continuousScanning option), which tried to work with the frame, after the frame had been removed from the document. This largely worked, except that, apparently, the window.getSelection function vanishes when a frame is no longer in the document.

Best,
Marijn

Wow!
Much appreciated.
Thanks for the fix to your awesome editor.
I'll update the demo ASAP.

Cheers!
Tony
