Fri, 10 Apr 2026 18:27:15 +0000 https://bugs.horde.org/ticket/2343 Calendar display problem when using shared calendars I'm using kronolith-FRAMEWORK_3-2005-07-26 In the calendar view, the following error is displayed when in 'My Calendars' a local and a remote calendar is enabled; Fatal error: Call to a member function on a non-object in /usr/lib/php/Horde/Kolab.php on line 261 this also happens when 2 remote calendars are enabled this error does not show up when only 2 local calendars are enabled. Wed, 27 Jul 2005 07:04:20 +0000 https://bugs.horde.org/ticket/2343#t10053 In addition to the problem before; if I only select one remote calendar it will actually display a full calendar without errors, but no calendar items are displayed. Wed, 27 Jul 2005 10:23:05 +0000 https://bugs.horde.org/ticket/2343#t10055 Are you actually using Kolab as a backend for your local calendars? Wed, 27 Jul 2005 12:12:09 +0000 https://bugs.horde.org/ticket/2343#t10062 Yes, I am. I am using Kolab 2.0rc4 which is running on a separate server. Calendars, mail, notes and tasks are working fine when not shared, as soon as I share a calendar the problem occurs. I'm not sure if this also happens with shared notes/tasks, I will test this tomorrow. Wed, 27 Jul 2005 13:21:56 +0000 https://bugs.horde.org/ticket/2343#t10068 Some additional info: the horde server is a gentoo machine running apache 2.0.54-r1 mod_php-4.4.0 horde versions: horde-FRAMEWORK_3-2005-07-21 framework-FRAMEWORK_3-2005-07-26 imp-FRAMEWORK_3-2005-07-21 turba-FRAMEWORK_3-2005-07-21 kronolith-FRAMEWORK_3-2005-07-26 mnemo-FRAMEWORK_3-2005-07-26 nag-FRAMEWORK_3-2005-07-26 I've tested the following: I start with 2 users, nothing shared and only their own calendar, notes, tasks enabled in the 'show lists' dropdown box, everything works fine. the same 2 users, user 1 shares his notes, user 2 enables his own notes and the notes of user 1 in the 'show notes' dropdown box, this throws a white page with this error: Fatal error: Call to a member function on a non-object in /usr/lib/php/Horde/Kolab.php on line 1485 I fiddled around a bit to see where the problem might be, I discovered that when, logged in as user 1, give access to a user using the 'permissions' button but don't click the 'change' button afterwards, permissions are only set in horde itself and not on the imap server. In this case user 2 can actually have notes of both users on the notes page, no errors show up. if I, logged in as user 1, set permissions using the 'permissions' button and after that hit the 'change' button, these messages will show: Horde/Kolab: Successfully synchronised notepad "Notes" The notepad "Notes" has been saved. this seems correct behaviour, but user 2 will then see this error: Fatal error: Call to a member function on a non-object in /usr/lib/php/Horde/Kolab.php on line 1485 the same happens when setting permissions on a calendar. but when sharing a calendar I can never get a local and a remote calendar to be shown at the same time, with and without imap permissions set (I tried setting and removing them manually with cyradm on the kolab server). when, being user 2, trying to display a calendar from user 1 and my own calendar, the following error shows: Fatal error: Call to a member function on a non-object in /usr/lib/php/Horde/Kolab.php on line 261 in this case no calendar is shown on the page, not even a blank one. when I select only user 1's calendar in the 'My Calendars' I can see a blank calendar but no events from user 1 are shown (of course I double checked to see if there were any events in user 1's calendar... that is the case ;) I also tried setting and removing permissions on the INBOX/Calendar mailbox on the kolab server manually but in all cases it showed the same behaviour. in short: notes and tasks seem to work fine when shared as long as the permissions on the imap server are not set. tasks on shared calendars won't show at all with or without permissions set on the imap server and displaying a local and a remote calendar at the same time doesn't work at all. I hope this will give a bit more insight in these problems, don't hesitate to ask if you need more info. Thu, 28 Jul 2005 00:23:09 +0000 https://bugs.horde.org/ticket/2343#t10089 I've just test the CVS version of the Kolab.php file here : http://cvs.horde.org/co.php/framework/Kolab/Kolab.php?r=1.26.10.9&p=1 It works fine from now. Mon, 28 Nov 2005 11:59:29 +0000 https://bugs.horde.org/ticket/2343#t14189 taco, can you confirm this? Mon, 28 Nov 2005 12:28:02 +0000 https://bugs.horde.org/ticket/2343#t14191 I'll try it first thing tomorrow, I'll post my findings here. Thanks for the efford so far! :) Mon, 28 Nov 2005 12:38:44 +0000 https://bugs.horde.org/ticket/2343#t14192 I just tested it, it all seems to work fine now! I will have a few local users test it a bit more, I'll post back here in a week or so to let you know if all went well. Again, thanks very much for all your effort! Mon, 28 Nov 2005 22:53:09 +0000 https://bugs.horde.org/ticket/2343#t14298 Great. Just add a comment if you find this not working.
