I believe qualifiers work the same regardless of in-memory or database
operation.
So, I think your EOKeyValueQualifier (typing from memory) would be something
like
EOQualifier qual = new EOKeyValueQualifier("rosterMembers.resource.tosuser",
EOQualifier.QualifierOperatorEqual,
thisUser);
NSMutableArray results = (NSMutableArray)
EOQualifier.filteredArrayWithQualifier(portfolio.projects(),qual);
The gotcha here, of course, is that it will silently fail if there is a typo
in the keypath. Should the above be touser rather than tosuser?

I am not doing this qualifier against the sql but against the array from a
relationship..
Does that relationship follow the key paths?
NSMutableArray results =
(NSMutableArray) EOQualifier.filteredArrayWithQualifier(
portfolio.projects(),andQualifier);
or does it have to be a fetch?

What I do is create a EOKeyValueQualifier. I almost never use
qualifierWithQualifierFormat because my qualifications tend to "too
specific." By that I mean I don't need the flexibility of qWQF.

Subject: EOQualifier Question
I have a relationship like so:
project -->> rostermembers <<--> resource <--> user
should this work?:
args.addObject("rosterMembers.resource.tosuser");
args.addObject(thisUser);
myQualifier3 = EOQualifier.qualifierWithQualifierFormat("%@ = %@",
args);
I can't seem to get this qualifier to work..
Wondering if this is actually possible to find those projects?
