content css ignored after setData in CKEditor

Question

I get the text and add some classes to spans. setData updates the content but the content css is not applied.

I can inspect(in Chrome) and see the new classes. I toggle on a Drupal page between flat text and WYSIWYG(disable-enable rich text) and it looks fine.

it is as if the editor forgets or stops applying the content css on setData

I tried:

 function submitaftersetdata() { this.updateElement(); this.checkdirty; CKEDITOR.config.contentsCss = 'http://www.mooyai.com/sites/all/modules/custom/languagetool/atd-ckeditor/atd.css'; alert('done'); } editor.setData(editorContents, submitaftersetdata); 

 editor.insertHtml(editorContents); 

works fine to add the new text and looks correct(the content css is applied)

setData to empty '' then insert works but again breaks the css

Answer 1

I found a weak work around:

 editor.execCommand( 'selectAll' ); editor.insertHtml(editorContents);
