I have the nice ckeditor 4 editor built into grapesjs with this components:

grapesjs: 0.15.8 grapesjs-preset-newsletter: 0.2.20 ckeditor.js: 4 grapesjs-plugin-ckeditor - 0.0.9

My project generates newsletters (HTML + CSS) to be storage in database. This newsletter it can be edited and save it again as many times as you want. When the newsletter is finished editing, it can be sent by Gmail.

My problem is this:

1. User generate newsletter (html + css) and is save it as "html + css" inline getted with; var htmlWithCss = editor.runCommand('gjs-get-inlined-html');

2. This is saved in database.

3. For edit the newsletter, the code is getted from database and is pushed in editor 3.1 Insert html+css inline in DOM

var component = angular.element('#gjs-mail');
component.append(htmlWithCss);

3.2 Init grapesJS over #gjs-mail

At this momment is all fine, the HTML+CSS is loaded at grapesjs editor. The problem come it when i try edit text with CKEDITOR4. The words seems are block and is difficult format text.

i have read a possible error origin, and is the form that i save the code, like tell this post:
