Ticket #278 (task)

From the caldav mailing list. This behavior needs testing in bedework

The description in the spec is correct. Here is an example that shows why:

Let's say you have a weekly recurring meeting every Monday.

One instance is shifted to a Tuesday

Now you do a time-range query for 8 days starting on a Monday and extending to the week of the overridden instance.

The server is required to return the master component (the one with the RRULE) to cover the first Monday in the time-range.

However, if that is all it did, then the client would see the weekly RRULE and assume that there is an instance on the second Monday, which would be wrong.

Instead the server has to return the overridden instance as well and that correctly shows the client that there is no second Monday instance.
