"// However you are creating or fetching the EO"
Yeah, this is the problem area I'm running into. I'm having a hard
time creating an EOEditingContext.
This is my first real customization of a class and I've never had to
reference the editing context before...
Maybe the question should be "How do I create/use and editing context
in Java Client?

Hi all,
I know this has to be an incredibly simple thing to do, but I
can't seem to figure out how.
All I want to do is defaults so that when an object is
instantiated, it automatically has some of it's relationships
defined. It is VERY easy to do this for an attribute, but I just
can't get it to work for a relationship and I can't find in the
documentation how to do it.
I know the code belongs in the awakeFromInsertion() method.
Can anyone give me a pointer to where in the documentation to look
for this, or better yet a simple code fragment?
BTW, this is for a Java Client application, but I don't think that
matters, right?
With JavaClient, who knows? :-)
public void awakeFromInsertion(EOEditingContext ec) {
super.awakeFromInsertion(); // do first
RelatedObject ro = // However you are creating or fetching the EO
// I am assuming that eo is now fetched or inserted into ec
addObjectToBothSidesOfRelationshipWithKey(ro, "relatedObject");
}
That is how I do it.
