URL is correct and entity is not nil.

So, all the other objects leading to the fetch execute look OK? Your
context isn't nil? Does your context actually have the right store
coordinator with the right store URL? Does NSEntityDescription return
an entity, and not nil? Does your context have a managed object model?

Here is the code in MyDocument:
-(IBAction)calculateStat:(id)sender{
fetchedObjects = nil;
context = [self managedObjectContext];
fetchRequest = [[NSFetchRequest alloc] init];
entity = [NSEntityDescription entityForName:@"Measurement"
inManagedObjectContext:context];
[fetchRequest setEntity:entity];
fetchedObjects = [context executeFetchRequest:fetchRequest
error:&error];
if (fetchedObjects == nil) {
NSLog(@"error");
[errorMessage setStringValue:@"no objects"];
}else {
[errorMessage setIntValue:[fetchedObjects count]];
}
[fetchRequest release];
The fetchedObjects count is always 0. Any idea what silly thing I
forgot.
