Error: Can't execute code from a freed script

Are you using the latest release of the editor ? I definitely came across this during initial integration of the release candidate but have since moved to the latest release and don't remember encountering this error since? Could be totally unrelated but worth checking.....

I was having the same problem, and had all but given up on FCKeditor. Thanks for the fix! This should definitely be included in the next release.

In addition to what was mentioned above, if you use the FCKeditorAPI, you will also need to execute:
FCKeditorAPI = null;
every time you load the editor into the page with your Ajax call, or you will get the "can't execute code from a freed script" error.

I have fix:) The problem seems to stem from the fact that certain FCK javascript variables & objects are loaded into the parent page, while others into iframes, etc. If FCK is loaded into the page, then removed, then loaded back into the same page (a common operation in Ajax), the parent vars are still present, while iframe vars are not(?).

The fix is to remove the FCK javascript object in the parent, thus making FCK reset. This did the trick for me:

__FCKeditorNS = null;

I'm sure the FCK developers did not envision its use in ajax, and did not imagine this kind of process flow.

Fantastic solution! Like dewoods I was about to give up on FCKeditor as it just wasn't working with my framework. Thankfully it is now!

Pleeease can we incorporate this as a more explicit reset() or cleanup() function into the next release of FCKeditor??

Also I think there might be a little more cleanup to be done: each usage of FCKeditor leaves behind a growing list of iframes in the DOM (you can see them using Mozilla's DOM inspector).

These iframes hold the style/formatting values used in the editor: "normal", "formatted", "address", etc, etc.

At the moment I'm clearing these out manually - unless anyone has a better solution.

As mentioned above, the ideal solution is to have a cleanup() method that takes care of everything... as everyone's jumping on the AJAX bandwagon these days its imperative that FCKeditor keeps up.

Anyway - good work ridewinter!

I'm sorry for the (stupid) question but how do you clear the iframes?
I added __FCKeditorNS = null; and FCKeditorAPI = null; but it is not enough for me

Hello Dear:
I haver the same problem, I'm new to ajax, i used it in an internal website, and now when i try to incorporate FCKeditor... PAF !!! don't load when using ajax.

My lame question is:

"Where" need i put the "__FCKeditorNS = null;" sentense ?

Thank's in advance and sorry about my low understanding of this technology :-/

The line of code " __FCKeditorNS = null; " should simply be executed in the page that holds FCKEditor. For example, right above where you instantiate FCKEditor, you could put:

<script language='javascript'>
__FCKeditorNS = null;
</script>

<?php
include_once("FCKeditor/fckeditor.php") ;
$oFCKeditor = new FCKeditor("test") ;
$oFCKeditor->Create() ;
?> 

To load FCKEditor 2.3 via Ajax requires an additional command to be run in the parent window:

__FCKeditorNS = null;
FCKeditorAPI = null;

I know, I know, it's a hack, but the FCKEditor developers still don't seem to have Ajax in mind...

What about the Toolbar Sharing feature. Once you've created and destroyed the editor, the toolbar remains there.

After recreating the editor, the main toolbar doesn't work anymore:
FCK is not defined
FCK_TRISTATE_DISABLED is not defined

Any ideas?

Have you found any other vars that need to be reset?

Please, I have no idea what is wrong

I'm having the same error. I'm using the latest build, 2.0, loaded into the page via ajax. The first time it loads without a problem. The second time it comes up with an error. The same problem occurs in both FF & IE.

Will post if I find a solution.
