You are doing something like this?
MyEO newEO = new MyEO();
editingContext.insertObject(newEO);
newEO = oldEO;
editingContext.saveChanges()?
I don't think you can just set the objects equal like that. You would
want to call all of the getters and setters for the properties, i.e.:
newEO.setMyProperty(oldEO.myProperty());
Does that help?

No, The diamond was checked off and the primary key field is invisible

Should I manually nullify the primary key in the application with the
diamond checked in the EOModel?
I didn't try it yet, because it doesn't look proper way for me.
I found my email was a bit blurred.
When modifying a record, I want to make the duplication with new
primary key.
So I inserted a new object and set the modifying record to the new
object to allow to be edited
and then do saveChanges(). The primary key of the original records
are also set to
the new object but I was expecting the primary key will be set as new
automatically when saveChanges().
Or there may be another method to do this? (Sorry I don't know the way
to find a proper method in the API
documents)

This can cause EOF to try to update a primary key, which causes
exception fever.

Hi there,
WO 5.2
Mac OS X10.3.4
Postgresql7.3.4 (pg73jdbc.jar)
When modifying an existing record in a table I want to keep the
existing record as it is,
because it might be used (relationed) to the other records in the
other table.
What I've tried was :
Show details of a record which is going to be modified
Insert new object into the table
Copy the details of record to the inserted object
and saveChanges()
But it gets primary key duplication error.
And I tried search on web/mailing list but I couldn't find any clue.
I even doesn't know what would be the keyword for search this issue.
Any help would be very much appreciated.
