hi.
i am using zimbra 6.0.7 and lightning 1.02b.
i have just found something that is, i think a bug, and i wish to know if this is known, fixed in a different version, or should i open a bug on this.

if you use the zimbra web interface to schedule a meeting, and afterwards move this meeting earlier, the alarm for that meeting is not changed.

now, i do not know if this is a lightning bug or zimbra bug. but when i accept the change in lightning i get "ERROR_MODIFICATION"
a little debuging showed me that lightning gives out this error:
[calAlarmService] alarm is in the future.
[calAlarmService] alarm is too late.
and then comes the crash that prevents lightning from editing the event:
Error: this.checkDavResourceType is not a function

can anyone confirm? explain? give pointers on how to fix?

thanks.
