Data processor removes not alphanumeric strings

[giammin]

refering to this ticket:

​http://dev.ckeditor.com/ticket/10298

this is not fixed.

i experience the same problem with

element.addClass('cke_blabla')
element.attributes.add('class','cke_blabla')
editor.insertHtml('<div class="cke_blabla">dfgdfg</div>')

those class names are removed

[Jakub Ś]

Class names starting with "cke_" are classes used by CKEditor. Editor uses them in WYSIWYG and removes when you e.g. switch to source mode. Please treat them like reserved keyword and use other namespace e.g. "mycke_".

If you still get Problems with classes please read about ACF: ​http://ckeditor.com/blog/Upgrading-to-CKEditor-4.1

if it is not an issue (although, I think it is because in my plugin I was using the same ckeditor css naming convention and I can't) it should be mentioned in the documentation AFAIK
