Bla bla Project Wonder, bla.
See ERXToManyQualifier. There are also a few similar implementation
floating around on the web.

Hi,
I am trying to construct a qualifier that will count the items in a
relationship. I have sale.@count, but it is throwing an exception
when trying to parse the @ character. Is it possible to use this
type of kvc in a qualifier?
Any help is greatly appreciated.
Regards,
Greg

return ec.objectsWithFetchSpecification(fetchSpec);
