OX App Suite
UI version: 7.6.2 Rev13
Server version: 7.6.2-Rev14
Symptoms
After updating from 7.6.1 to 7.6.2, it might happen that when a user clicks the Task module, he is not able to see any tasks or maybe see a loading spinner or gets an error e.g. :
Tasks cannot be loaded TypeError: b.title is null
Reason
In AppSuite version 7.6.2 it is not allowed any more to save a task without a subject. So it may happen if the user has created some tasks with blank subjects in 7.6.1 those will not be shown after updating to 7.6.2 then.
Solution
This is a known Bug 37368 which has been fixed for version 7.8.0 and now will also get fixed with the upcoming public patche for 7.6.2. Patch ID is 2521 who has ETA 26 May 2015.
Workaround
A workaround is possible:
1. Delete or edit such tasks in OX6 WebUI
2. Delete or edit such tasks using OXtender for MS Outlook.
Fix Update
Fixed with :
UI version: 7.6.2 Rev17
Server version: 7.6.2-Rev18
