I can confirm that after upgrading to the latest code via PEAR, the 
problem no longer is reproducible.

Thank you for solving the issue!

Best regards & "case closed"

I'm on a business trip ATM - the upgrade will probably take place next 
week and I'll provide feedback right after.

Cannot reproduce.

Cannot reproduce this with current stable code.

The "completed_date" field was removed in 2011 because it is not part 
of the Kolab 2.0 format. See: 
https://github.com/horde/horde/commit/109a2bd69de0f88d9008ccc3ed4d8a092cb4095f#diff-0ef97c65debfe55ccb3b62b3056c3712
It doesn't look like we don't consider the "status" field at all in 
code, but rather look at if the Kolab "completed" field is empty 
(not-completed) or non-empty (completed). This is not correct though 
because this field should be a percentage of completion so technically 
a non-empty field could still be considered "not-complete".

So, I'm not sure why those tasks are still showing as non-completed, 
since we are only looking at the "completed" field when considering 
this and according to your data, that part at least looks correct.

It should be noted that your nag version is quite a number of bug 
fixes behind current stable code, including a number of Kolab related 
fixes. Please upgrade to the latest stable and retest.

sorry, seems I need more coffee:

The tasks that are still listed in the portal widget were mostly 
created using earlier versions of Horde, i.e. July 2013 and marked 
completed in Nov 2013, with then current Horde versions.

New entries, like the one I just mentioned, now *also* do not 
disappear from the list, especially not from the portal widget. The 
widget configuration *does not* have "always show completed and future 
tasks" checked.

yes, I just reproduced by

- creating a new task via Horde web ui
- look at NAGs "unfinished tasks" list and see the new entry
- click the "finished" check mark

- The task then is still listed, but in strike-out

- clicking on the task to display the details, the "completed" 
check-box is checked.

Are both tasks created/completed by Horde?

For some releases now (cannot tell since when - about 2 months, I 
guess), my existing tasks are not recognized as "completed", and thus 
are displayed even when selecting to display only pending tasks.

All those tasks do show the "completed" checkmark as "checked".

We're using the Kolab backend to store the task data.

When completing new events, this feature works.

Comparing an old and a new completed task in the IMAP store, I see the 
following difference:

--- cut here: old entry ---
   <completed>100</completed>
   <status>not-started</status>
   <due-date>2010-01-15T10:00:00Z</due-date>
   <completed_date>2010-01-19T16:07:48Z</completed_date>
--- cut here ---

--- cut here: new entry ---
=20=20<priority>3</priority>
=20=20<completed>100</completed>
=20=20<status>completed</status>
=20=20<due-date>2015-02-27T01:00:00Z</due-date>
--- cut here ---

So the old entry has, for whatever reason, a status of "not started", 
but does have a "completed_date". Sounds weird, but worked with older 
version of Horde.

The new entry has no "completed_date" (which sounds like an error to 
me - missing information!), but a status of "completed".

From the user interface, both events look alike, but filtering the 
view seems to have changed to work on "status" now (which seems like a 
proper decision, of course).

I see the following two problems:

1. How can we mass-migrated the status of old tasks to "completed" for 
all those entries that have a "completed_date" set?

2. No longer having the "completed_date" in new entries seems like a 
bug to me.
