[icalendar-dev] Error in treatment of the EXDATE

[Luthiger Stoll Benno]

Looking at the code (prop.TypesFactory) I see that the EXDATE (and the
RDATE) property is treated as a single date-time value and processed
using the vDDDTypes factory. The iCalendar product does not allow for
list of date-time values. (Well, it allows such  lists, but doesn't care
of all but the first value.) This contradicts the RFC2445 specs which
clearly allow for a list of (comma separated) of date-time values.

 

I propose to create a new class vDDDLists to handle lists of vDDDTypes
values.

 

I could implement this solution and provide a patch.

Is it possible to apply the patch and to create a new release of the
iCalendar product?

 

Regards,

Benno

Hello

I've found out the following error concerning the treatment of the
EXDATE element.

According to the RFC2445 specs, the following statement is allowed:

===

BEGIN:VEVENT

...

EXDATE:20071103T110000Z,20071104T110000Z,20071105T110000Z

...

END:VEVENT

===

When I use iCalender to interpret this statement, however, I get the
following result:

===

>>> calendar = Calendar.from_string(ics)

>>> events = calendar.walk('VEVENT')

>>> for event in events:

...     print event.decoded('EXDATE')

2007-11-03 11:00:00+00:00

===

Whereas I expect a list of datetime values, the icalendar object returns
only the first value.

Regards,

Benno Luthiger
