Faulting should happen automatically. What you are doing works for me.
You are sure that the the PortfolioGroup and Portfolio are in the same
editing context when doing the in memory filtering.

P.S. Stylistically I am compelled so suggest:
EOQualifier portfolioQualifier =
EOQualifier.qualifierWithQualifierFormat("porfolio = %@", new
NSArray(porfolio));
over
EOQualifier myQualifier2;
NSMutableArray args2 = new NSMutableArray();
args2.addObject("portfolio");
args2.addObject(portfolio);
myQualifier2 = EOQualifier.qualifierWithQualifierFormat("%@ = %@",
args2);

Hello -
Why is it when I do a qualifier on a related array I get nothing back
but when I do a fetch I get the correct
result?
This works:
EOQualifier myQualifier1;
NSMutableArray args1 = new NSMutableArray();
args1.addObject("user");
args1.addObject(this);
myQualifier1 = EOQualifier.qualifierWithQualifierFormat("%@ = %@",
args1);
EOQualifier myQualifier2;
NSMutableArray args2 = new NSMutableArray();
args2.addObject("portfolio");
args2.addObject(portfolio);
myQualifier2 = EOQualifier.qualifierWithQualifierFormat("%@ = %@",
args2);
EOAndQualifier andQualifier1 = new EOAndQualifier(new NSArray(new
Object[]{myQualifier1,myQualifier2}));
EOFetchSpecification fs = new
EOFetchSpecification("PortfolioUserGroup",andQualifier1,null);
NSMutableArray results = (NSMutableArray)
this.editingContext().objectsWithFetchSpecification(fs);
While this won't. Why?
Object nameOrdering = null;
EOQualifier myQualifier;
NSMutableArray args = new NSMutableArray();
args.addObject("portfolio");
args.addObject(portfolio);
myQualifier = EOQualifier.qualifierWithQualifierFormat("%@ = %@",
args);
NSMutableArray results =
(NSMutableArray)EOQualifier.filteredArrayWithQualifier(portfolioUserGro
ups(), myQualifier);
the porftfolioUserGroups() is a relation that points portfolios to
users to groups. The original array it returns is correct but when
I qualify it with the portfolio it returns nothing. I have checked
that the portfolio is correct and the array is correct. I am guessing
it has to do with faulting. Is there some deep fault switch I am
missing?
