Status: RESOLVED WORKSFORME

(Calendar :: Calendar Frontend, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de; rv:1.8.1.4) Gecko/20070529 SUSE/2.0.0.4-8.3 Firefox/2.0.0.4

The display of appointments doesn't work after update to V0.5. 

I have to say that I'm using a "degenerated" method, only using external calendars (ics files). Which worked perfectly in previous versions.

Reproducible: Always

Steps to Reproduce:
1. Start Sunbird -> everything ok
2. Switch view or just switch time frame, e.g. next month
3. Appointments vanish
Actual Results:  
No display of appointments any more. Seems like only an initial view is updated. Any action that would need a screen update doesn't do this update.

Expected Results:  
Show the appointments after scrolling or switching views

Worked in earlier versions.

I found a work around or rather the reason for this behaviour. In my list of calendars (about 10-12 external ICS files) there was one for which the respective server was offline. I was aware of this fact, but this never caused any problem for earlier versions.

So the preliminary explanation is, that if one of the files can't be opened, the update problem will be there. Also it will be there for ALL calendars! De-activating the calendar coming from this server (the one which is not readable) lets disappear the problem. 

This is definately different from earlier versions and I'm not sure if it is (should be) the desired behaviour of the software.

We have seen in other bug reports, that this might be due to the use of a proxy on the network.  Reporter, are you using a proxy on your network?

I have no proxy configured in the Sunbird settings. In the company network there is a transparent proxy active though.

The CalDAV server which was causing the problem is in the internal network. So my guess is that there should be no proxy involved.

I also see this behavior, and I don't have a proxy involved (just NAT'ed gateways). However, I have noticed that its not prompting for my password on the WebDAV server.

I have to turn off all remote calendars and restart Thunderbird 1.5.0.12 before I can see any local ones.

This was working in Lightning 0.3.1 until I upgraded to 0.5 build 2007062504.

We got a similar problem. There is only one ICS calendar in the list, but not one event is shown, even when initializing.

The external calendar is loaded, Apache's log contains the GET request. But Lightning doesn't show anything, and gives no error message.

There also is a proxy in the network - when disabling it it works!

Bug 393387 was fixed a few days ago and might help with the issue reported here too. I'd like you to retest with a Sunbird or Lightning 0.7pre (20070918) or newer build if your issue still exists.

Does the issue still exists using Sunbird 0.7 Release Candidate 1?
<http://releases.mozilla.org/pub/mozilla.org/calendar/sunbird/releases/0.7rc1/>

Comment 9

[Stefan Sitter [:ssitter]]

Reporter, please post the retest results with Sunbird 0.7 resp. Lightning 0.7. Otherwise I assume the issue is fixed now and this bug can be resolved.

No response from reporter in several months. Resolving as WFM assuming that the issue has been solved in 0.7. Feel free to reopen the bug if the issue can be reproduced in a recent 0.8pre nightly build.
