#12727 closed Bug (fixed)

IndexSizeError on using plugins 'Div Editing Area' and 'Content Templates'

Reported by: onion.net Owned by:
Priority: Normal Milestone: CKEditor 4.5.7
Component: General Version: 4.4.6
Keywords: Blink Cc: jacobvanlingen@…, glen.84@…

Description

This error occurs in Chrome (Version 39.0.2171.71) running on Windows 7 x64.

I created a basic CKEditor and added Div Editing Area, Image and Content Templates as plugins.

Reproduce the error:

  1. Open the template dialog and select the first default template ('Image and Title'). The dialog closes an the template gets displayed.
  2. Open the template dialog again and select the second template ('Strange Template'). The dialog stays visible.

The developer console shows the following error:
Uncaught IndexSizeError: Failed to execute 'extend' on 'Selection': 1 is larger than the given node's length. (in ckeditor.js)

Problem can be reproduced from CKEditor 4.4.6 in Blink Browsers. Divarea is also required to reproduce this problem.

I have the same problem.

I found that this error occurs when the moveNativeSelectionToBookmark() function calls to selection.extend() with the offset longer than node.length.

If I surround the extend call with a "try/catch" block or an "if" block checking the parameters, it avoids this error.

I had several complaints as well, and it seems like the workaround suggested by dlopezp helped.

I'm running into this same problem now with a fresh install of v4.4.7. I'd like to try out dlopezp's suggested fix, but can't find the moveNativeSelectionToBookmark function. Is that in the core ckeditor file or part of one of the plugins mentioned above?

It is located in core/selection.js

You need source version for it: http://docs.ckeditor.com/#!/guide/dev_source, after making the change you need to build CKEditor http://docs.ckeditor.com/#!/guide/dev_build

Any update on this issue? I'm also getting this error. Wouldn't it be wiser to understand why the error happens, instead of swallowing it with a try-catch? Nevertheless, any solution to this issue will be appreciated.

Any update about it, I still found the same error in our current version. ​http://stackoverflow.com/questions/29886961/ckeditor-error-uncaught-indexsizeerror-failed-to-execute-extend-on-selectio Thanks.

Wake up! This bug makes Div Editing Area mode unusable! From version 4.4.6 to actual 4.5.3...

I too have this error. It happens whenever I press ok on a custom iframedialog.
So I cant give an example.
The code of the error is below and is being executed after the following events:
click(on Ok button dialog) -> [dialog plugin]ok -> [dialog]saveSnapshot -> [undo plugin]beforeUndoImage followed by afterUndoImage

The error occures in selection.js:224

function moveNativeSelectionToBookmark( document, bm ) {
   var sel = document.getSelection(),
   range = document.createRange();

   range.setStart( bm[ 0 ].node, bm[ 0 ].offset );
   range.collapse( true );
   sel.removeAllRanges();
   sel.addRange( range );
   sel.extend( bm[ 1 ].node, bm[ 1 ].offset ); << error
}

Where bm[1].node is a TextNode with text =""
and bm[1].offset is 1

I don't know why the extend throws an exception, can't find it's workings.

It is possible this bug is related to #10031 because it happens on chrome when the current selection is character &#8203(ZERO WIDTH SPACE U+200B)

Milestone: CKEditor 4.5.4

We've got #13513 and #13284 assigned to 4.5.4 already. Both are on review and both have a chance to fix this issue as well. But let's keep track of this ticket as well (I'm assigning it to 4.5.4).

PS. Please note that this is very complicated issue caused by even more complicated hack for Webkit and Blink bugs. We may not be able to succeed in closing every type of this issue in one release.

Just like in http://dev.ckeditor.com/ticket/13377#comment:17 – we need a bit more time, but it's finally looking promising.

This issue will be fixed by #13816 in the next milestone.

Thanks for working on this. I get it when clicking a "Add Post" button, after adding the post I want to clear the content but this error stops setData("") from working for roughly 120ms

Submitting with the keyboard doesn't cause the error so it must be an issue with blur

Anyone have any ideas how to fix this before 4.5.6?
