JS error when editing a non-https image in CKEditor when hosted on https (SSL) in IE8

[Philippe Meunier]

We have a website which uses https (SSL) and CKEditor 3.6 runs within. The image plugin is enabled. When we load some content in CKEditor, and that content contains non-html images, a popup occurs under IE8, which ask if we want to load only secured content (and omit non-secure content). We answer yes. Some images are missing but still outlined in CKEditor. If we double click one of these image, the image dialog opens. If we try to accept the content of the dialog, it fails.

Please provide the following when reporting new bugs. The more information you provide, the quicker the bug may be solved:

Browser name and OS : Internet Explorer 8 in Windows XP

1. Paste (in html page) into textarea the following code.

   <p><img alt="" src="http://www.google.com/images/logos/ps_logo2.png" style="width: 364px; height: 126px" /></p>
   

2. Open replacebycode sample in https and answer yes when IE asks you whether you want to load only secure content.
3. Display image properties dialog.

Result: JS error is thrown:

Message: 'undefined' is empty or not an object
Row: 561
Char: 14
URI: /3.6/ckeditor/_source/plugins/image/dialogs/image.js

and you are not able to close the dialog by clicking OK.

You also are not able to close the image dialog with “OK” when you open the page in https, open image dialog, paste the following link - ​http://www.google.com/images/logos/ps_logo2.png and answer yes when IE asks you whether you want to load only secure content.

This has worked that way in IE8 from CKEditor 3.0

For non-ssl resources work in WYSIWYG mode via https, you need to answer "no" on IE8's confirmation dialog, otherwise the image will not load and browser will prevent to alter it's src attribute, we can hardly do anything that helps.

What makes this issue critical is that the dialog gets stuck, which can cause data loss. We need to at least avoid the js error, making the dialog still usable, even if missing some feature.

IE6, CKEditor rev7024 - problem still occurs:

• I answered No in IE6 confirmation dialog
• Opened Image properties.
• Without making any changes press OK

Result: JS error visible in IE status-bar
