"I'm trying to upload an image to an object relation using the AJAX feature. The upload itself seems to work, but when the relation objets is to be added I get this error message:

Unable to parse the JSON response.

I use 2012.8."

Steps to reproduce

In the backend, edit an object with a content object relation attribute.
Add a file, and try to upload. You will get the error message "Unable to parse the JSON response."
