are you .... sure? are you using the same version of NSDictionary that is in wonder trunk? that's impossible, basically, unless that dictionary is being attacked by multiple threads and you'e in the middle of a race condition .......

Hi all, was a nice WOWODC, and really nice Job done Pascal.



I have a small Problem about NSDictionary.

NSArray<Movie> movies= Movie.fetchAllMovies(defaultEditingContext());
EOEnterpriseObject eo = movies.objectAtIndex(0);
NSDictionary pDic = EOUtilities.primaryKeyForObject(defaultEditingContext(), eo);
System.err.println("1:" + pDic); -->1:{movieID = 102; }
System.err.println("isEmpty:" + pDic.isEmpty()); -->isEmpty:true
System.err.println("count:" + pDic.count()); -->count:1


Hadn't isEmpty not to be false ?

Also looking into isEmpty 

public int count() {
return _count;
}

public boolean isEmpty() {
System.err.println("_count : " + _count); -->_count : 0
System.err.println("count() : " + count()); -->count : 1

return _count <= 0;
}


Why is the result of _count and count() different?

Any ideas what's going wrong?






Thank you
