- Go to a document in CMS
- tag it using plugin interface, e.g. auto, car, bmw
- save document
- re-edit document, removing middle tag 'car'
- now document is tagged like auto, , bmw
- click save in CMS > this will lead to a 500 error for that specific user.
- expected: a pop-up / warning that syntax used is incorrect ór
- expected that plugin will rewrite tags set to auto, bmw automatically thus preventing complete failure of CMS.
