I have a basic parent entity with two child entities. I set up a nib
file using the default "entity" interface for all three. I can add and
remove data fine, but for some reason, the search fields that are
automatically provided do not work, and in fact cause the following
error message:
Can't use in/contains operator with collection FIRST (not a collection)
I don't really know what the message refers to since I don't have a
"FIRST" entity. (There is a "first" attribute (lower case), but I was
not searching on that attribute anyway.) This happens regardless of
whether I search a parent or child entity.
Is "FIRST" how Core Data sets up the automatically provided filter
predicates (FIRST, SECOND, etc.)? Googling this came no with no
matches at all.
Also, I wanted to examine the filter predicates associated with the
search field, but I can't find a way to do that. Is there a way to
modify them?
Finally, can anyone shed light on this error message?
Thanks.
Daniel
