I have a problem with using Hibernate Spatial and PostGIS. I have an entity with a field like this:
public class LocationBean {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;
@Type(type = "org.hibernate.spatial.GeometryType")
private Point location;
}
The problem I have is that I can't load any of these entities from the database, unless location is null for that entity. If it is not null, I get the following error:
Exception: Can't convert object of type org.postgresql.util.PGobject
javax.el.ELException: /protected/topPanel/searchBar.xhtml @27,57 completeMethod="#{toppanelbb.completeSearchBar}": java.lang.IllegalArgumentException: Can't convert object of type org.postgresql.util.PGobject

The weird thing is that I can persist them just fine, but not load them. For example, if I do something like:
LocationBean loc = new LocationBean();
loc.setLocation(new GeometryFactory.createPoint(new Coordinate(lon, lat));
// persist to db...
The point is correctly stored correctly in the Postgresql database and querying it works. Only when I load it, it doesn't work.
I can also load other fields from the class, besides the location field. So for instance:
Query query = em.createQuery("SELECT l.id from LocationBean l WHERE within(v.location, :filter) = true", Long.class);
would work, but:
Query query = em.createQuery("SELECT l from LocationBean l WHERE within(v.location, :filter) = true", LocationBean.class);
would not.
These are the dependencies in my pom.xml:

<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.3.5.Final</version>

</dependency>
Any ideas what I could try? I have a workaround solution at the moment, where I only use the persisted GeometryType for querying, but don't ever load it into a java object, but I am not happy with that solution. Thanks!
