438866 - Accept / Decline buttons have disappeared in Lightning

Status: VERIFIED DUPLICATE of bug 403768

(Calendar :: Lightning Only, defect)

Description

[Simon Wistow]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.14) Gecko/20080404 Firefox/2.0.0.14
Build Identifier: Thunderbird 2.0.0.14 (20080421) / Lightning 0.9pre (2008060820)

When I receive meeting requests with an .ics file attached I no longer get any Accept or Decline buttons in the mail.

Reproducible: Always

Steps to Reproduce:
1.
2.
3.
Actual Results:  
A mail with a meeting request from Outlook/Exchange arrives. It has an .ics file attachment but no Accept/Decline buttons are show. Double clicking on the file causes an error

Error: [Exception... "'Failure' when calling method: [nsICommandLineHandler::handle]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "<unknown>"  data: no]

Saving the file and then importing it directly from Lightning works as expected.

Expected Results:  
When a mail with an ics attachment arrives I should see Accept/Decline buttons. Clicking on Accept should import the VEVENTS in the ics file into my default calendar.

This used to work for me but has stopped recently. I can't absolutely confirm it but I seem to recall that it stopped working after I accidentally deleted my default calendar and then recreated it. 

My default calendar is an internal calendar (as opposed to several other calendars which are remote ICS files) with the identifier moz-profile-calendar://?id=2 - could this be the problem? 

I was originally using 0.8 but attempted to fix the problem by uninstalling it and installing one of the nightlies (0.9pre 2008060820) to see if that fixed the problem but this had no effect.

With regards to the error message - I've checked the ICS file and the Location: property is set correctly (I'm only guessing that that is what it's talking about but I could be wrong)

Please ensure that menu option "View -> Display Attachments inline" is enabled.

You're absolutely right. That solved the problem. Now I just feel incredibly dumb :)

Although some sort of FAQ or alternatively, a warning from Lightning might be useful.

Thanks!
