335817 - Loading of calendar causes calIcalComponent.startTime errors

Status: RESOLVED INVALID

(Calendar :: General, defect)

Description

[Steve Wardell]

I'm using 2006042807 1.8 branch Lightning build with 1.8 Branch Thunderbird. I'm connecting to a Remote Calendar on a CommunicatePro server. Once it authenticates and connects, I end up with dozens of popup errors. It seems like it does not fully load the calendar entries.  The following errors showing serveral times in the JavaScript console:

Error: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [calIIcalComponent.startTime]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: file:///C:/Documents%20and%20Settings/Steve/Application%20Data/Thunderbird/Profiles/default/ztlnigmk.slt/extensions/%7Be2fda1a4-762b-4020-b5ad-a41df1933103%7D/components/calItemBase.js :: anonymous :: line 480"  data: no]

Line: 480

Let me know if there's additional information that is needed on this issue.

I'd bet heavily that the calendar you're subscribing to puts the startTime of an event in a timezone that isn't declared.  Find the TZID in the starttime, and look for a VTIMEZONE component that corresponds to it.  If the VTIMEZONE isn't there, the file is invalid.

Can you have a look at this and clarify the incorrect behavior? I'll try to get an issue opened with CommuniGate on this issue once I understand it better. Thanks.

Actually, here's an event that shows a timezone:

Ok, I found one incorrect item. Removed it and still having problems. Is it possible for Calendar to catch the problematic events and show which event it has a problem with to make tracking such things easier?

From the little sample event I saw the following:

At the beginning the timezone is defined like:
    BEGIN:VTIMEZONE
    TZID:(GMT-05:00) Eastern Time (US & Canada)

Later in the file the timezone is used:
    DTSTART;TZID="(GMT-05:00) Eastern Time (US & Canada)":20060121T090000

The problem is that once quotation marks around the timezone are used and once not. If I add them to the timezone definition like:
    BEGIN:VTIMEZONE
    TZID:"(GMT-05:00) Eastern Time (US & Canada)"

no error dialog is displayed and I even see an alarm popup.
