Hello,
I have a to-one relationship that is giving me problems when updating the
destination entity.
class Seo
{
id; <- PK
title;
description;
state() <- reverse to-one relationship to State
}
class State
{
id; <- PK
name;
seoid; <- FK to Seo (id)
seo(); <- optional to-one relationship to Seo
}
When I first enter an Seo to a State, all seems fine, all properties of Seo
are saved and are related to the corresponding State. But then, when I
update it I get this exception.
Unable to map destination State for relationship state in entity Seo. To
one relationships must be joined on the primary key of the destination.
java.lang.IllegalArgumentException: Unable to map destination State for
relationship state in entity Seo. To one relationships must be joined on
the primary key of the destination.

Is my entity modeling correct? Any ideas how I can resolve this?
Thanks,
