Without information on how you are using it and the model, you leave
us guessing.
Well, as I am left guessing, I guess that the framework is not
getting initialized correctly. Did you add the framework like a
normal WO framework?

How I can create a query where
project can have ( Items(a) OR Items(b) ) AND (Items(c))
Something like this...
NSMutableArray itemsAQuals = new NSMutableArray();
String keyPathToA = "blah.blah";
for ( Item a : itemsA ) {
itemsAQuals.addObject( new EOKeyValueQualifier( keyPathToA,
EOQualifier.QualifierOperatorContains, a ) );
}
etc...
EOQualifier q = new EOAndQualifier( new NSArray( new Object[] {
new EOOrQualifier(new NSArray(new Object[] {
new EOAndQualifier( itemsAQuals ),
new EOAndQualifier( itemsBQuals )
} ) ),
new EOAndQualifier( itemsCQuals )
} ) );
That will work in memory, but
EOQualifier.QualifierOperatorContains won't generate correct SQL
for most databases. Do you use one that this works on?
