Hi there,
with ERXEOControlUtilities.objectCountForToManyRelationship I have bumped into
a weird problem — with newly created EOs it fails, yelling that “... is not a
toMany relationship! Expected an NSArray, but got null” (exact copy below).
Now, perhaps I do something wrong, but it seems to me it is perfectly normal in
EOF that all to-manys of a newly created EO are null? At the very least,
whenever I checked, they were.
So far, the only fix I have found is to refault the newly created object
immediately, which helps (fetch replaces those nulls by empty arrays), but it
is pretty ugly:
===
DBDataBlock bc=... create new EO and insert it into an EC ...
... set it up ...
if (!ec.saveChanges()) return ERROR...
bc.editingContext.refaultObject(bc) // <==== this helps. Without this
line, to-manys are nulls now
===
Is there any better solution?
And what am I overlooking? To me, the check for null in
objectCountForToManyRelationship looks like a bug.
Thanks a lot,
OC
