Description Jose 2009-04-03 14:42:28 UTC

Version:           4.2.2 (using 4.2.2 (KDE 4.2.2), Kubuntu packages)
Compiler:          cc
OS:                Linux (i686) release 2.6.27-11-server

I'm using an Akonadi backend with a ics file to store tasks. When I add a subtask it is added as a first class task, instead of as a child of the task that I added it to. If I change the view, sometimes I get the correct view but it seems to be random. When I change the subtask state, it's automatically detached from its parent and it cannot be attached again.
It does not happen if I add the resource as a external calendar file, instead of an Akonadi source.

I reproduced this with akonadi/korganizer-4.2.2.

I also got this crash while creating a sub-todo:

Comment 4 Vitor M. Pereira 2011-05-12 11:23:12 UTC

Has there been any development in this issue?
I'm still seeing this problem in kdepim 4.4.11 with sub-todos in calendars from akonadi. Since I use quite a lot of sub-todos this forces me to use "Calendar in Local File" resources.

Comment 5 Sergio Martins 2011-05-12 18:46:45 UTC

Fixed in master and 4.6 branch.
