Robert Munteanu commented on SLING-5763:
----------------------------------------
Hm, that version is pretty old. Could you quickly try the latest 9-SNAPSHOT
version of the Sling Launchpad and see if that fixes your problem? Looking at
the commit log for the `scripting.jsp` bundle I can spot at least SLING-3405
and SLING-3724 as related to your problem.
