All Editor buttons disabled after exiting the source mode

[dan turcu]

When I enter the source mode, and exit, all the buttons of the editor are disabled, for some contents.

I discovered the real problem. The buttons are disabled if the attribute data-widget="image" is present in a <a> tag. This attribute is used by mobile devices, to know that a link is pointing to an image.

Also this problems appears only if the widget plugin is present in the editor.

Could you describe this problem in more detail?

If you go to ​http://ckeditor.com/demo#widgets and click inside a widget (best text under image2 widget) you will see that most buttons get disabled. This is correct behaviour as there are only certain elements that can be put into nested contenteditable.

The issue , is that , if I have a tag in the source of the form : <a data-widget="image" href="some_link">some text</a> when you will enter the source mode and then you will exit to the source mode : you will get all the editor buttons disabled.

The steps to reproduce this problem are :

1. Go to ​http://ckeditor.com/demo#widgets
2. Enter source mode in the Enhanced Image and add this line anywhere in the source : <a data-widget="image" href="​http://www.google.com">some text</a>
3. Exit the source mode and you'll see that all the editor buttons are now disabled

I know that the data-widget attribute is used internally by the editor but in our application we use this attribute to tell mobile device, that the link is pointing an image.

Steps to reproduce:

1. Set config.allowedContent = true; for editor
2. Load image2 sample
3. Switch to source mode and paste <a data-widget="image" href="​http://www.google.com">some text</a>
4. Switch to WYSIWYG

Result: JS error is thrown (thus all buttons get disabled)

Problem can be reproduced from CKEditor 4.3
