For relationships you can put something like the method shown below in
your custom EO subclass. One set of the eogen templates out there have
this too IIRC. I added the check for ec changes since the count might
be inaccurate otherwise and will definitely fail for new unsaved
objects.....
/**
* This method is protected since they are to be called by
eogenerated templates.
* If object not saved, uses standard array count, otherwise uses
database count
*
* @param key
* @return count for the given relationship.
*/
protected Integer countForRelationship(String key)
{
if (editingContext().hasChanges()) {
return (Integer) valueForKeyPath(key + "....@count");
} else {
EOQualifier qual = qualifierForRelationshipWithKey(key);
String anEntityName = this.entityName();
EOEntity anEntity =
EOModelGroup.defaultGroup().entityNamed(anEntityName);
EORelationship aRelationship =
anEntity.relationshipNamed(key);
return
ERXEOControlUtilities.objectCountWithQualifier(this.editingContext(),
aRelationship
.destinationEntity().name(), qual);
}
}

Hi Jerry,
It appears that wocode is no longer there.
Can you possibly post the CountFetcher.java code here or some other
easy to access place?
Thanks!

Hi, Miguel,
You might try CountFetcher.java which can be downloaded from:

Hi!
This is probably very obvious, but... how can I count the objects
that would be retuned by a fetch specification, but without
actually fetching them (or creating faults for them)? What I would
like to do is something like the COUNT SQL function.
