[CalendarServer-users] iMIP replies… (hack solution)

[Markus Stürmer]

After spending some more time I was able to identify the problem.

The error emerges from file
	CalendarServer/twistedcaldav/scheduling/implicit.py
class ImplicitScheduler's member function
	def extractCalendarData(self)
in line
306                     for item in  
self.originatorPrincipal.calendarUserAddresses():

To be honest, I do not fully understand the interdependencies in DCS.  
But from what I understand the problem arises in that line:
303                 self.originatorPrincipal = (yield  
self.request.locateResource(originatorPrincipalURL))

If I schedule an event, locateResource usually returns an object of  
type "DirectoryCalendarPrincipalResource" describing the  
originator==organizer of the event. I did not verify that, but from  
what I've read every DirectoryCalendarPrincipalResource should have at  
least some urn / guid - type cuaddr-esses and possibly email addresses.

But during imip mail injection, an object of type  
"DirectoryPrincipalResource" is returned which lacks the  
"calenderUserAddresses()" member function (although it is refers to  
the iMIP injection user).

So my workaround was to change
304                 if self.originatorPrincipal:
into
304                 if self.originatorPrincipal and  
hasattr(self.originatorPrincipal,'calendarUserAddresses'):

That way mail injection works, *BUT* I am not sure which problems  
could arise later if self.originator (self is an ImplicitScheduler)  
remains "" as initialized in line 298.

Regards,
Markus
