Yeah, that's true, me too. I actually have used the Houdah one more

It looks like a bug to me. I mix the Wonder and Houdah qualifiers, and I don't
recall which one I have used for this in the past or where I used
There's a simple way if you have a A ->> B, to fetch all the A's having no B's :
EOQualifier qual = ERXQ.isNull(A.TO_BS_KEY + "." + B.ID_KEY);
Beware, the to-many relationship must be of type "Left Outer" in your model
Hope it helps.

But i'm curious to hear from the others, is there someone else using this

Hope it helps,

Hi,
John is right, if you have A ->> B, this should work :

EOQualifier qual = new ERXExistsQualifier( ERXQ.isNotNull(B.A_FK_KEY) ,
A.TO_BS_KEY);
ERXFetchSpecification spec = new ERXFetchSpecification(A.ENTITY_NAME,
qual, null);
(not tested though)
hope it helps

I think you can do this with ERXExistsQualifier and a Not qualifier.

Hey all,
Maybe I missed something but is there a way to construct a qualifier that
check that a toMany relationship is empty? Simply putting in "toMany =%@,
new NSArray(new Object[] {NSKeyValueCoding.NullValue}doesn't do it because
it tries to check across the join table which results in no obje
