When you create a new Routing, is it getting inserted into an EC?
This method is not called until that is done.

Okay, Here's my code:
public void awakeFromInsertion (EOEditingContext ec) {
super.awakeFromInsertion(ec);
EOFetchSpecification fs =
EOFetchSpecification.fetchSpecificationNamed("Task","RoutingType");
NSArray routingTypes = ec.objectsWithFetchSpecification(fs);
System.out.println(routingTypes.objectAtIndex(0).toString());
setRoutingType((EOGenericRecord)routingTypes.objectAtIndex(0));
}
It's not working at all. No errors at least, but it doesn't appear
to be being called either because when I create a new Routing in
the UI, it doesn't set the default value, and I don't get the
message printed out in the console either.
It's nearly midnight here. I'm going to bed. Maybe I'll have
inspiration in the morning.

IIRC, EOAccess is not available client side.

Hmmm...
When I try to import the eoaccess package, I get this error at
compile-time:
src/com/bestmaid/erp/client/Routing.java:10: package
com.webobjects.eoaccess does not exist
import com.webobjects.eoaccess.*;
The JavaEOAccess.framework is part of the project and part of the
Web Server target, as is the Routing.java file.
I don't understand why it sees the other packages (eocontrol,
foudation) but not eoaccess.
Any ideas?

David,
Besides calling the set method in awakeFromInsertion(), I can't
imagine what else there is to do. Of course, you need to get
the EO in the correct editing context. Since the EC is passed
into the awakeFromInsertion() method, you could:
public void awakeFromInsertion(EOEditingContext ec) {
MyObject obj = EOUtilities.objectMatchingKeyandValue(ec,
"ENTITY", "KEY", "VALUE");
setRelObj(obj);
}
I've never done Java client, but I would assume this will work...

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?
