That seems like a bug to me. Maybe that's why I still don't use
display groups. :-)
From my interpretation of the documentation on WODisplayGroup this
does not sound like a bug to me. The method displayGroup.allObjects
() contains an array of objects fetched into the display group.
There are a few methods that can change the collection, but
qualifyDisplayGroup() is not one of them. The method
qualifyDisplayGroup() does an "in-memory" filter of the allObjects
collection, so reporting from allObjects() still contains all
objects fetched. Using qualifyDisplayGroup() with a different
qualifier still needs access to the fetched collection since it
does not fetch from the data source.
If you use qualifyDataSource() instead of qualifyDisplayGroup() a
fetch does occur and allObjects() will receive a newly qualified
collection.
It is certainly the case that the features of that class work as
described; the bug is in the fact that there is no way (except object
rape) to get the count of the in-memory-filtered objects.
