This is a annoying bug. We also have the same issue.

I've traced it down to the file js/clone.js and specific line 245:

tinymce.execCommand( 'mceAddEditor', true, this.id );

When removing this line, the drag and drop is successful, however the tab visual is switch to text, and the editor show the html instead of the styled text.

Hope this helps the journey into this bug.

Adding editor.execCommand('mceSetContent', false, this.id); above tinymce.execCommand( 'mceAddEditor', true, this.id ); (line 245) does seem to fix the problem of the content being swapped.

The tabs are still scambled (see my previous post)

@edwinsiebel
What is 'editor' in editor.execCommand('mceSetContent', false, this.id);?

[edwinsiebel]

@viet34tqc , never mind my reaction. The editor.execCommand('mceSetContent', false, this.id); returns an error, so that's why tinymce.execCommand( 'mceAddEditor', true, this.id ); was not executed, and thus that 'fixes' what I wrote in #1381 (comment).

Any research or improvements on this post?

Hi,

This is an old issue and it seems to be fixed in the latest version of Meta Box and extensions. So I'll close the issue.

If you still notice the bug, please re-open it.
