#1965 closed Bug (fixed)

SpellerPages crashes IE 7

Reported by: Thomas Messier Owned by: Frederico Caldeira Knabben

Component: UI : Spell Checker Version: FCKeditor 2.6 Beta
Keywords: Confirmed IE Review+ Cc:


When I run spell check using SpellerPages IE crashes (always). Basically, I run a spellcheck and once I get the popup that the spellcheck is complete, I click on the OK button and that's when the crash occurs. I'm using Windows XP SP2 and my IE version is 7.0.5730.11.

Confirmed in IE7. FF2 doesn't seem to be effected by this bug. As IE7 crashes I'm getting this report:

The bug also occurs in IE6, but in this case the browser just freezes and refuses o respond.

This may be related to another case: The 2nd patch: which was not part of the downloaded package I got resolved a similar issue in Ie6 where the browser crashes after the spellCheck dialog self-closes.

I tested the patch from the comment above to see if it would solve the problem and it doesn't.

I'm have no problems with IE7. With IE6 instead, I' having an Access Denied error. So, something is definitely wrong here.

Much probably it depends on selection related things, because of the new dialog system.

comment:5 Changed 16 years ago by Nader

I believe the Access Denied error may be related to the mixed-mode warning in IE6 when using "javascript:void(0)" as the source of an iFrame. If I remember correctly from when I got around this issue a week or so ago -- the script attempts to access the contents of an iFrame set to "javascript:void(0)" while the security dialog is still just about to be displayed. This was occurring for me on a SSL server. Try changing the iframe within the spellCheck dialog file to a "blank.html" file and see if it works.

Most of the iframes needed to be converted to reference a "blank.html" as on SSL servers and Ie, you get mixed-mode warnings for using "javascript:void(0)"

I was able to get around both issues, the spellCheck works fine in Ie6/7 and FF2 in the modified copy I have.

It seems that the OnSelectionChange event firing was entering in concurrence with something else at the end of the spell checking process, probably with the SetData function.

The proposed patch simply delays the event firing execution. No more errors have been thrown in this way, and there should be no penalty to the rest of the code because of it.

Replying to naderf:

Fortunately we have fixed all HTTPS issues without having to use an empty page. It is just a matter of using the right URL for it, which is different for each browser. Check out the FCKTools.GetVoidUrl() function definition in the fcktools.js file.

Btw, the proposed patch has been checked over HTTPS with no warnings.

I guess that this one should be OK for the moment, but we must remember it for the V3 event handling

also there are some spelling mistakes: cuncurrency vs concurrency and "t obe" vs "to be"
