Hello -

I have a many-to-many relationship as such:

Portfolio --->>MetricGroups--->>MetricItems<----project_item---- >Project

How I can create a query where

project can have ( Items(a) OR Items(b) ) AND (Items(c))
or even
(items(a) or items(b) or ... items(x)) AND (items (c) or items (d)) AND (items(e))

well you get the picture.

I can seem to figure how to nest the "and" and "or" qualifiers to get expected results.

Or, was there an EOQualifier extension someone wrote to handle such a query?

I _think_ what you want is ExistsInRelationshipQualifier. Get it from Pierre Bernard's Houdah WebObjects Frameworks (formerly from his Qualifier Additions):
