Thanks Jerry.
I had thought of using setObjectArray but the documentation turned me
off, it says:
"... should almost never need to be invoked explicitly"
'whatever', I used it as:
transactions.setObjectArray( new NSArray() );
transactions.updateDisplayedObjects();
and it behaved just as I wanted.
For further lurkers, after implementing:
if ( mYear.noNeedToFetch() ) {
transactions.setObjectArray( new NSArray() );
transactions.updateDisplayedObjects();
} else {
....
I didn't see any big improvement over the previous version of the app
which did a fetch across 100's of records only to return none.

Hi, Baiss,
I think that setObjectArray() will do the job for you.
Reagards,
Jerry

How do I clear the objects out of <WODisplayGroup.allObjects()> so
that an <updateDisplayedObjects()> will be the empty set, without
doing a <fetch>?
