375267 - lightning extension silently fails when invalid ICS remote calendar URL is given

Status: RESOLVED DUPLICATE of bug 314594

(Calendar :: Provider: ICS/WebDAV, defect)

Description

[Duncan]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3
Build Identifier: 0.3.1 and 0.5pre (nightly build)

Lightning adds new calendar with an URL containing bogus server or path name.  Even though no such calendar path exists, no error message is given and a blank calendar is displayed!
Tested with 0.3.1 (official) and 0.5pre (nightly build from today 25. Mar. 2007).

Because manual URL entry is very prone to misspellings, I have set this to Major.


Reproducible: Always

Steps to Reproduce:
1. Add "New..." calendar
2. Select "On the Network"
3. Leave Format on "iCalendar (ICS)"
4. Enter valid URL to a web site you have WebDav access to, but enter WRONG PATH name OR enter a completely bogus site: e.g.: https://www.ical.com/ica.ics
Actual Results:  
Component finishes and shows blank calendar (urk...)

Expected Results:  
When the path name on the server is incorrect, no calendar can be created.  The component should return error: invalid/mispelled URL and recover gracefully, e.g.: show the URL entry dialog again and give the user to change the URL.  It should not fail silently and it should not show an empty calendar (suggesting that everything is fine, which it isn't obviously).

Note: if you do not have a webdav enabled site, but use a bogus url with a real site address (e.g.: https://mail.google.com/temp.ics) then it will give you a read only error.  That is not what I am trying to pin down here though.
