Anyone know why I can't have a relationship called 'members'?
When I have a flattened many-to-many where one of the relationships is called 'members' and I try to add an object to the relationship with addObjectToBothSidesOfRelationshipWithKey(obj, "members") I get the following cryptic error message:
java.lang.IllegalArgumentException: addObjectToPropertyWithKey: the key members is not null, an NSArray or one of its subclasses - unable to add the value.
Interestingly, I also get a similar error message if I try to add the object to the other side of the relationship. However, if I change the name of my relationship to 'foo' it all works fine.
Of course it took me a few hours to figure this out.... I guess 'members' conflicts with something else.
Cheers,
Jake
