Hello Chuck:
Mark the id attribute as Allows Null and then make the
relationship optional.
If the attribute is a primary key attribute and of a numeric type
(ex. integer type), then you cannot set it to allow null.
I got the same error as David.
Mike is working on a fix in Entity Modeler, I believe.
Perhaps I don't understand how you are modeling this. A PK to PK
relationship can't be optional. A PK to FK relationship can be
optional, but is a properly a to-many relationship.
I messed up in various ways in looking at this problem. The first was
that it was one of my very first models using EOModeler, so I had the
relationship running backwards. How this worked correctly in the
past, I really don't know. The second way that I messed up was that
my Eclipse build was picking up changes in the /Library/Frameworks
directory, not in my project. This led to me trying all sorts of
modeling behaviour in the framework project I was linked to that
wasn't showing up when I ran it. When I finally discovered that this
was happening...
How are you modeling this?
... I had already deleted the relationship entirely.

An application that I have converted from XCode to Eclipse is
throwing an error when I save a new document EO. I went back in
and looked at the old version of the model in the XCode app and
the relationship is marked as to-one optional. The entity
modeler version is mandatory to-one and if I try to set it back
to optional, it gives me a warning: "The relationship
documentContent is optional but the attribute id does not allow
nulls". What do I need to do to model this correctly and/or get
rid of the error on save?
Mark the id attribute as Allows Null and then make the
relationship optional.
