James,
Your example code example is fine and it's fully supported to create
an EOQualifier this way. Since the qualifier format parser is quite
flexible, I don't think any type mismatch issues can be caught at
compile time.

Hmmm,
And to think I learned that method of qualifier creation from either
a book or Apples own docs years ago.
But mixing the objects in the List was confusing me, which is what
Johann said about just using <Object>

I completely disagree on this one. Your example is bad as it mixes
different type of objects in the List. The point of generics is to
catch type cast exception at compile time instead of run time. if
you mix objects in the same array then it has no value but this is
bad style anyway.

Well I have decided to to start going to 1.5 now.
this is something I do all the time:
NSMutableArray args2 = new NSMutableArray();
args2.addObject("portfolio");
args2.addObject(portfolio);
myQualifier2 = EOQualifier.qualifierWithQualifierFormat("%@ =
%@", args2);
NSArray results =
EOQualifier
.filteredArrayWithQualifier(portfolioUserGroups(),myQualifier2);
How do I make that "generic Java 1.5" friendly?

YMMV :-)
