Lightning 1.8a1 (custom build) with Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/16.0 Thunderbird/16.0a1 (BuildID: 20120607030200) Steps to reproduce: 1. create a new Thunderbird profile 2. install Lightning extension 3. create event in the default Home calendar and invite attendees Result: No event invitation is send. Error console shows: Error: 'TypeError: aItem.calendar.canNotify is not a function' when calling method: [calIOperationListener::onOperationComplete] = NS_ERROR_XPC_JS_THREW_JS_OBJECT Source file: resource://calendar/modules/calProviderUtils.jsm Line: 650 Lightning 1.5 works. After creating the event the Outlook compatibility dialog is shown and afterwards the email is send. Maybe Lightning 1.6 or Lightning 1.7 are affected too but I cannot specify regression range due to the lack of nightly builds. Maybe related to Bug 751923.

Lightning 1.7 shows the same problem.

I think the problem is that canNotify() is declared in calISchedulingSupport but this interface is not implemented by calStorageCalendar. What would be the correct fix? Implement calISchedulingSupport in calStorageCalendar?

Isn't it implemented by calProviderBase?

I see now. Seems that we need to announce the interfaces too we get via __proto__ from cal.ProviderBase.prototype.

I upgraded to thunderbird 15.0 and Lightning 1.7 a few days ago. Now I tried to create an event in local calendar and invite a partner, isn't send email and isn't error on the console. When I deleted the event, then an e-mail notification is sended. I repeated the process, but this time I used a google calendar synchronized through CALDAV. I created the event, and invited a partner, isn't send the email and error appear in the console saying: Fecha y hora: 31/08/2012 10:36:37 Error: [Exception... "'TypeError: aItem.calendar.canNotify is not a function' when calling method: [calIOperationListener::onOperationComplete]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "JS frame :: resource://calendar/modules/calProviderUtils.jsm :: cPB_notifyOperationComplete :: line 650" data: no] Archivo de origen: resource://calendar/modules/calProviderUtils.jsm Línea: 650 I verify the file of the url https://hg.mozilla.org/releases/comm-aurora/rev/5c55719c34fd with my local copy of the calStorageCalendar.js and has been corrected, but the error isn't resolved. Please can help me?

Julián, this was a problem with storage provider and has been fixed. But according to your description you are using caldav provider and not storage provider. Please check if there is already a bug report for caldav provider and file an new bug report if not.
