Hello Jerry,
Hi, Xavier,
It would help to know how your code is failing, but I don't see why
your code wouldn't work so long as "arg" is an NSArray.
The code is not failing in fact, it's just there's no result return.
If arg is an instance of Connector rather than an NSArray, then
change your qualifier generating statement to the following:
EOQualifer myQualifier = EOQualifer.qualifierWithQualifierFormat
("connectors = %@", new NSArray(arg));
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
Regards,
Jerry

Hi,
I don't know if I'm doing it wrong or if I'm just misuse
EOQualifier but:
I have an entity a with a flattened manyToMany relationship named
connectors on a connector entity.
I need to qualify a fetch on entity a based on having connector %@
so basically I was doing
EOQualifer.qualifierWithQualifierFormat("connectors = %@", arg);
arg having a connector entity.
But this doesn't seemed to work...
Am I doing this wrong?
Thanks
Xavier
