Flask-CKEditor - Error code: editor-element-conflict - flask

Question

In my flask app, I have 2 instances of CKEditor on 2 different files.
<div>
{{ ckeditor.create(name="message_body") }}
{{ ckeditor.load(pkg_type="standard") }}
{{ ckeditor.config(name="message_body", width=1000, height=500) }}
</div>
and
<div>
{{ ckeditor.create(name="newsletter_body") }}
{{ ckeditor.load(pkg_type="standard") }}
{{ ckeditor.config(name="newsletter_body", width=1000, height=500) }}
</div>
Each of those <div> are in a {% block main %}
I'm getting the data from from 2 different file with these lines:
request.form.get("message_body")
and
request.form.get("newsletter_body")
All seems fine, I get the data but in my browser I get this errors:
[CKEDITOR] Error code: editor-element-conflict.
Object { editorName: "message_body" }
The related docs read this:
Description: There is already an editor’s instance attached to the provided element and attaching another one to it is not allowed.
Additional data:
editorName: The name of the already attached editor.
But I don't understand why. Can any one help me get rid of these errors?
Many thanks

I just release 0.4.5 to fix this, please upgrade:
pip install -U flask-ckeditor
The reason behind this error is:
When you add a "ckeditor" class to a textarea element, CKEditor will try to initialize a CKEditor editor box on top of it. At the same time, if you initialize a CKEditor editor box manually with CKEDITOR.replace(...) (which is what the ckeditor.config() does), the error happens: you can't initialize two CKEditor editor box on one textarea element.
