I having problems saving many to many relationships to a pivot table.
The way the pojos are created is unfortunately a pretty long process which spans over a couple of different threads which work on the (to this point un-saved) object until it is finally persisted. I associate the related objects to one another right after they are created and when debugging I can see the List of related object populated with their respective objects. So basically all is fine to this point. When I persist the object everything get saved except the relations in the pivot table.
mapping files:
<?xml version="1.0" encoding="UTF-8"?>

and the other

pojos:
public class ShowObject extends OrmObject
{
private Long id;
private String name;
private Set venues;
public ShowObject()
{
}
public Long getId()
{
return id;
}
public void setId(Long id)
{
this.id = id;
}
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
public Set getVenues()
{
return venues;
}
public void setVenues(Set venues)
{
this.venues = venues;
}
}
and the other:
public class VenueObject extends OrmObject
{
private Long id;
private String name;
private int latitude;
private int longitude;
private Set shows = new HashSet();
public VenueObject()
{
}
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
public Long getId()
{
return id;
}
public void setId(Long id)
{
this.id = id;
}
public int getLatitude()
{
return latitude;
}
public void setLatitude(int latitude)
{
this.latitude = latitude;
}
public int getLongitude()
{
return longitude;
}
public void setLongitude(int longitude)
{
this.longitude = longitude;
}
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
public Set getShows()
{
return shows;
}
public void setShows(Set shows)
{
this.shows = shows;
}
}
Might the problem be related to the lack of annotations?
