Whoops! My Javadoc has lead you astray. Change the "modelCopy" call to
"deepCopy". So:
@Override
public Agenda duplicate(NSMutableDictionary<EOGlobalID, ERXCopyable<?>>
copiedObjects) {
Agenda duplicate = ERXCopyable.Utility.deepCopy(copiedObjects, (Agenda)
this);
return duplicate;
}
In order to use the "modelCopy" method, you need to add entries Agenda's
UserInfo dictionary in your EOModel which I'm guessing you haven't done.
Once you've done that, calling anInstanceOfAgenda.copy() will create a new
instance of Agenda EO in the same EC as anInstanceOfAgenda and then copy all
the attributes and relationships from anInstanceOfAgenda to the new instance.
You then need to make all the related Entities implement ERXCopyable as well.
The deepCopy assumes that you want copies of all of Agenda's related EOs also,
which may or may not be true (probably not). If it is not true, you will need
to change the duplicate method to do what is correct for Agenda and its related
EOs. If you have Practical WebObjects, read Chapter 9, with special attention
to the Tweaking the Copy Process section on page 264.
Basically, you are going to want to use some combination of the various
ERXCopyable.Utility.xxxxCopyRelationship methods where xxxx could be
reference, shallow or deep. See the javadoc for an explanation of what each
will do.
I hope that helps you!
