The code is not failing in fact, it's just there's no result return.

Actually I was trying with an instance of connector, I also tried  
with an NSArray of connector but no luck.

Here's my code:
	argsStorage = new NSMutableArray();
	argsStorage.addObject(selectedFormFactor); // this is a toOne
	argsStorage.addObject(selectedFormType); // this is a toOne
	argsStorage.addObject(new NSArray(selectedConnector)); // this is  
the toMany that doesn't return any results
	qualStorage = EOQualifier.qualifierWithQualifierFormat 
("(productFormFactor = %@) and (productFormType = %@) and  
(productExternalConnectors = %@)", argsStorage);

Maybe that's easier to understand than my description;)

Thanks

Xavier
