Version: KOrganizer Version 4.2.1 and previous (using KDE 4.2.1) OS: Linux Installed from: SuSE RPMs in kde 3 finished tasks appeared in the journal since kde 4 it doesn't work
There's a setting for this, did you enable it? Settings->Configure KOrganizer->Views->Todo View->"Record completed to-dos in Journals"
Thanks It was not enabled. Its a bit hidden.
