Rich text editing is removed on all fields if a condition applied on any.
I can reproduce this issue, and happened to me in the following scenario:
I have a field collection on the content type:
which has 2 fields,
I set a conditions here, to show field_last once there is something in field_first.
It works great,
Now, we needed a second field_collection, a clone of the last one, that would appear separated from the first one (therefore unlimited setting is out of the solution).
So, I create:
And I import the same fields that I used at the other field_collection_1:
I set the conditions the same way, and wallaaa, when I'm trying to create a node that uses those two field_collections, breaks jquery and ckeditor along.
My guess is that is having problems with "different" field collections, having the same exact name for the fields... and I see that if I create different field names (not reusing) inside the field_collection_2, this problem doesn't happen.
if you update to the latest dev version it works! I am using wysiwyg 7.x-2.2+54-dev and CKEditor 126.96.36.199cdcad. I am using JQuery update to 1.8 version too.
This is still broken in the latest dev. It also breaks the display of the GMap module too.
I encountered this bug and was able to get things working by updating to the latest dev versions of Conditional Fields and WYSIWYG as well as updating CKEditor to version 4.4.7:
