Dan Allen resolved JBSEAM-2348.
-------------------------------

    Fix Version/s: 2.0.3.CR2
       Resolution: Done
           Labels: seam-gen  (was: )


The problem was that seam-gen didn't even acknowledge the possibility of a one-to-one mapping. Fortunately, from the standpoint of the UI, it can be treated just like a many-to-one property, and thus I just had to include both to-one relationships in the same function.

> Since I do use JBoss Tool I assume that this is cause by an error in the underlying seam generate-ui. It fails if you have entities annotated like this:
> public class User implements Serializable {
> 	@Id
> 	@GeneratedValue
> 	private Long id;
> 	@OneToOne
> 	@PrimaryKeyJoinColumn
> 	private UserData userData;
> }
> public class UserData implements Serializable {
> 	@Id
> 	private Long id;
> 	@OneToOne
> 	@PrimaryKeyJoinColumn
> 	private User user;
> }
> This will result in this Exception:
> org.eclipse.core.runtime.CoreException: org.hibernate.tool.hbm2x.ExporterException: Error while processing template view/list.xhtml.ftl
> org.eclipse.core.runtime.CoreException[666]: org.hibernate.tool.hbm2x.ExporterException: Error while processing template view/list.xhtml.ftl
> Caused by: freemarker.core.InvalidReferenceException: Expression property.value.typeName is undefined on line 39, column 6 in view/list.xhtml.ftl
