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.
