This is not possible... the only options for OneToMany fields are List, Set,
Map and Collection
I'm currently using the following workaround in my getter method:
public Set<SalePurchaser> getSalePurchaserSet()
{
if (!(salePurchaserSet instanceof SortedSet))
salePurchaserSet = new TreeSet<SalePurchaser>( salePurchaserSet
);
return salePurchaserSet;
}
