[eclipselink-users] The number of actual and formal parameters differs,
|
Hello,
I am trying to fix some problem with a boolean field. On some data, I
consistently get an exception on the first time I try to retrieve it
from the database. Here is my persistent class:
package be.uclouvain.doctorat.model.entity;
import be.uclouvain.doctorat.model.entity.util.WithDemande;
import be.uclouvain.doctorat.model.entity.util.WithId;
import be.uclouvain.doctorat.model.util.DecisionIntervenant;
import java.io.Serializable;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.EnumType;
import javax.persistence.Enumerated;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
@Entity
@Table(name = "commentaires")
public class Commentaire implements Serializable, WithDemande, WithId {
public static final long serialVersionUID = 2008051501;
private Long id;
private String commentaire;
private Date dateModification;
private boolean parDoctorant;
private Demande demande;
private Personne personne;
private boolean confidentiel;
private DecisionIntervenant decision;
public Commentaire() {
}
public String getCommentaire() {
return commentaire;
}
public void setCommentaire(String commentaire) {
this.commentaire = commentaire;
}
@Temporal(TemporalType.DATE)
@Column(name = "DATE_MODIFICATION")
public Date getDateModification() {
return dateModification;
}
public void setDateModification(Date dateModification) {
this.dateModification = dateModification;
}
@Id
@GeneratedValue(generator = "idSeq")
@SequenceGenerator(name = "idSeq", sequenceName = "IDENTIFIERS",
allocationSize = 1)
@Column(nullable = false)
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
@Column(name = "PAR_DOCTORANT", nullable = false)
public boolean isParDoctorant() {
return parDoctorant;
}
public void setParDoctorant(boolean parDoctorant) {
this.parDoctorant = parDoctorant;
}
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "DEMANDE_ID", referencedColumnName = "ID")
public Demande getDemande() {
return demande;
}
public void setDemande(Demande demande) {
this.demande = demande;
}
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "PERSONNE_ID", referencedColumnName = "ID")
public Personne getPersonne() {
return personne;
}
public void setPersonne(Personne personne) {
this.personne = personne;
}
@Column(name = "CONFIDENTIEL", nullable = false)
public boolean isConfidentiel() {
return confidentiel;
}
public void setConfidentiel(boolean param) {
this.confidentiel = param;
}
@Enumerated(EnumType.STRING)
public DecisionIntervenant getDecision() {
return decision;
}
public void setDecision(DecisionIntervenant decision) {
this.decision = decision;
}
public Commentaire dbCopy() {
Commentaire newCommentaire = new Commentaire();
newCommentaire.setDateModification(dateModification);
newCommentaire.setParDoctorant(parDoctorant);
newCommentaire.setDemande(demande);
newCommentaire.setPersonne(personne);
newCommentaire.setConfidentiel(confidentiel);
newCommentaire.setDecision(decision);
return newCommentaire;
}
@Override
public boolean equals(Object obj) {
if (obj == null) {
return false;
}
if (getClass() != obj.getClass()) {
return false;
}
final Commentaire other = (Commentaire) obj;
if (this.id != other.id && (this.id == null ||
!this.id.equals(other.id))) {
return false;
}
return true;
}
@Override
public int hashCode() {
int hash = 3;
hash = 59 * hash + (this.id != null ? this.id.hashCode() : 0);
return hash;
}
}
And the exception:
Exception Description: Trying to invoke [setParDoctorant] on the object
[0]. The number of actual and formal parameters differs, or an
unwrapping conversion has failed.
Internal Exception: java.lang.IllegalArgumentException
at
be.uclouvain.doctorat.model.service._IDemandeService_Wrapper.getCommentairesList(be/uclouvain/doctorat/model/service/_IDemandeService_Wrapper.java)
Any clue?
