MappedBy from 3.1 to 3.2

Hi,
I'm currently moving from hibernate 3.1 to 3.2 to comply ejb3 spec etc. On 3.1 everything was working fine, but now I receive this exception:

org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: be.fgov.onerva.hris.bo.IndividualData.rrnr1 in be.fgov.onerva.hris.bo.Agent.individualDataList

I have 2 relational tables, here is the summary :

Code:

COMMON_DATA_INDIVIDUAL{RRNR1,VALUEDATE,...}
COMMON_UNVERSIONABLE_DATA{RRNR1,...}

here are the mapping :

Code:

@Entity
@AccessType("field")
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "COMMON_DATA_INDIVIDUAL")
@IdClass(VersionableDataAgentPk.class)
public class IndividualData implements Serializable {

    @Id
    @ManyToOne
    private Integer rrnr1;

    @Id
    private Date valueDate;

Code:

@Embeddable
@AccessType("field")
public class VersionableDataAgentPk implements Serializable {

    @Basic
    @Column(name = "RRNR1")
    private Integer rrnr1;

    @Basic
    @Column(name = "VALUE_DATE", nullable = false)
    private Date valueDate;

Code:

@Entity @AccessType("field")
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "COMMON_UNVERSIONABLE_DATA")
public class Agent implements Serializable {

    @Id
    @Column(name = "RRNR1")
    private Integer rrnr1;

    @OneToMany(mappedBy = "rrnr1")    
    @JoinColumn(name = "RRNR1")
    @MapKey(name = "valueDate")
    @OrderBy(value = "valueDate")
    private Map<Date, IndividualData> individualDataList;

I try to set the targetEntity in the OneToMany, but that changes nothing...
rrnr1 is well in the IndividualData table... bu it can't find it ???
Any idea ?

Many thanks,
Vince.

this is not a valid construct

Code:

@Id
@ManyToOne
private Integer rrnr1;

hi im having the same problem - i just noticed i had old hibernate jars and just updated to the latest. heres whats happening:

org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: au.edu.qut.yawl.elements.data.YParameter.decomposition in au.edu.qut.yawl.elements.YDecomposition.inputParameters

heres the exception:

my class YDecomposition has these:

Code:

    @OneToMany(mappedBy="decomposition", cascade={CascadeType.ALL}, fetch = FetchType.EAGER)
    @OnDelete(action=OnDeleteAction.CASCADE)
    @Where(clause="direction='inputParam'")
    public List<YParameter> getInputParameters() {
       return _inputParameters;
   }

yparameter extends yvariable which has a getDecomposition() method:

Code:

    @ManyToOne
    public void setDecomposition(YDecomposition parent) {
       this.parent = parent;
    }
    
    public YDecomposition getDecomposition() {
       return parent;
    }
