Inline list edit does not work and throws Javascript errorDescriptionWhen trying to edit the value of a field in a list, an "Uncaught TypeError: Cannot call method 'isOKExtension' of null" exception is thrown and the loading image keeps spinning. This gives the impression to the end user that something is about to happen. See attachment.This problem has been identified as part of another known issue (PRB593900 / KB0538399), fixed in Eureka Patch 8 and onward:Non-admin users are unable to perform "list edit" from a list view of task records.As an itil user (but not as admin) the list edit hangs, and the loading image keeps spinning, giving the impression to the end user that something is about to happen.A TypeError is thrown onto the javascript console from the _checkSecurity function:Uncaught TypeError: Cannot call method 'isOKExtension' of null js_includes.jsx?v=02-11-2014_1308&lp=Tue_Apr_01_17_38_50_PDT_2014&c=4_147:34888Uncaught TypeError: object is not a function Steps to Reproduce An Itil user cannot edit a field from a Task list.Note that it works fine if editing as an admin, or on any extended field like Incident or Problem. Impersonate to an ITIL user or a user from a non-admin group. Click My Work or My Group Work under the Service Desk menu. Alternatively, we can also create My Work or My Group Work item under Incident or Request, and no filter is required for this test. Make sure the Enable list edit option is checked for the list. Double-click any field from the list. Note the loading image shows up but there is no pop-up window or field. Copy the record number from the list. Click Incident under the Service Desk menu and search for the same record. If you click the field, everything works fine and you are able to do a list edit. WorkaroundThere is no workaround for this Known Error at this time.Related Problem: PRB593224
