Status: VERIFIED WORKSFORME

(Calendar :: Tasks, defect)

Description

[Stefan Sitter [:ssitter]]

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.12pre) Gecko/2008012205 Calendar/0.8pre

Steps to Reproduce:
1. Start Sunbird with new clean profile
2. Subscribe to any ics calendar (e.g. empty .ics file on local disk or 
   <http://www.mozilla.org/projects/calendar/caldata/USHolidays.ics>)
3. Restart Sunbird and check the Error Console

Actual Results:
The following message is logged six times in the Error Console:

    Error: this.mTreeView.selection has no properties
    Source File: chrome://calendar/content/calendar-task-tree.xml
    Line: 151

Expected Results:
No error during startup.

Additional Information:
It doesn't matter if the .ics file contains tasks; the error is logged in any case. A corresponding Lightning build doesn't report the error.

I have also noticed this and it was my fault :) This is fixed by bug 379100, but this bug introduced a different problem with views in lightning (week view looks strange on first load).

I have this on my radar and will add a patch to 379100 soon, or file a new bug.
