I have installed the CMF sandbox by following this tutorial: http://symfony.com/doc/master/cmf/cookbook/editions/cmf_sandbox.html
I'm using Jackalope + Doctrine DBAL instead of Apache Jackrabbit and at first glance everything seems to be working.
The issue arises when I want to edit text. Editing h1 elements works fine but when I edit a block of text, the CKeditor does not show and in addition to that, the save button does not become clickable after making changes.
I switched to the Hallo editor and the main stuff (bold, italic etc. and save button) now works (links, image uploading don't work; the cancel button does not switch back to Browse mode when editing text and returns this error: Error: cannot call methods on button prior to initialization; attempted to call method 'refresh')
Same thing with the CMF standard edition.
You help is much appreciated, let me know if you need more information. Like I said, I followed the CMF doc step by step and all the assets seem to be properly installed under /web/bundles/cmfcreate/...
