Hi, Xavier,
The code should look like this:
================================================
argsStorage = new NSMutableArray();
argsStorage.addObject(selectedFormFactor); // this is a toOne
argsStorage.addObject(selectedFormType); // this is a toOne
argsStorage.addObject(selectedConnector); // this is the toMany that
doesn't return any results (NOTE CHANGE HERE)
qualStorage = EOQualifier.qualifierWithQualifierFormat
("(productFormFactor = %@) and (productFormType = %@) and
(productExternalConnectors = %@)", argsStorage);
// followed by something like:
EOFetchSpecification fetchSpec = new EOFetchSpecification
("MyEntity", qualStorage, null);
NSArray results = myEditingContext.objectsWithFetchSpecification
(fetchSpec);
================================================
My only point earlier was that the second argument to
qualifierWithQualifierFormat must be an NSArray (with a String as the
first argument). As an aside, the number of "%@" references in the
string must match the number of elements in the NSArray, but you seem
to be doing that.
I would suggest modifying your code to the above and adding the
runtime parameter:
-EOAdaptorDebugEnabled Yes
to your application startup. Check the SQL that's generated to
confirm that it selects the results you're looking for. If it seems
like it should and you're still not getting the results you expect,
then I would suspect a problem in the database (e.g. it doesn't have
the data or structure that you're expecting).
If the generated SQL does NOT conform to your expectations, then I
would suspect a problem with the EOModel.
Regards,
Jerry

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;)

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?
