Affects version (Component): Parent values: Cocoon Core(10151). Level 1

Fix version (Component): Parent values: Cocoon Core(10227). Level 1
values: 2.2.0-RC2(10303).
It turns out that commit made by Carsten in r543066 did not incorporate
essential change proposed originally by Alexander Klimetschek. This problem
turns out to be the reincarnation of COCOON-2070 that has never been fixed.
