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.
How are you modeling this?

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.
