I have yet to see *one* case where setting an array is actually
useful, since AFAIK you can't simply create an array, add a new EO,
set this array and expect to get a reasonable object graph.
I think you can actually. I can think of several times that I have
done this.
I *did* have a special NSArray class especially for relationships
that was "linked" to the EO, in that you could
someEO.someRelationship().addObject() to it and it would call up
someEO.addObjectToBothSides() for you, but it was a bitch to write
(like the two-side relationship stuff).

I have noticed that the default _wonder.java template does not
produce a method to assign an array to a toMany relationship, as:
public void setMyMany(NSArray value) {
takeStoredValueForKey(value, "myMany");
}
Is there a problem with doing so? Should I change my method to
delete all the current relationships, and then loop through the
updated array and use "addTo${relationship.capitalizedName}"
instead?
Thanks

This is more of a Wonder question. It is safe WRT to EOF to do
this. BUT ERXGenericRecord has some fancy relationship automagic
manipulation that may not work. It may work, I don't use it and I
don't recall offhand.
