I just tested out the hosted demo for 5.0 RC2, as I'm eagerly awaiting searchable calendars. However, the search only works within the current view (month), which makes the calendar search nearly worthless.
Access Denied is marked as fixed, and Bug 19338 - calendar list view doesn't mention calendar list view for searches.
Any ideas if this is coming, or does it need a new bug filed?
...Just have to say that I'm going to catch some heat for promising users that calendar search would be in 5.0, when it effectively isn't there (without a list view) :-(
