Hi,
I encoutered a trouble with hibernate entity stored into a process variable in jbpm 4.4...
I've got every time a lazy loading error for any property of a very simple entity :
@Entity
@Table(name = "DAY_OFF_TYPE")
public class DayOffType extends AbstractEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "ID")
private Long id;
@Column(name = "KEY_LABEL", nullable = false)
private String keyLabel;
@Column(name = "PDF_TYPE", nullable = true)
private String pdfType;
@Column(name= "AVAILABILITY")
@Enumerated(EnumType.STRING)
private TypeOfAvailability availability;
public void setAvailability(TypeOfAvailability availability) {
this.availability = availability;
}
public TypeOfAvailability getAvailability() {
return availability;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getKeyLabel() {
return keyLabel;
}
public void setKeyLabel(String keyLabel) {
this.keyLabel = keyLabel;
}
public String getPdfType() {
return pdfType;
}
public void setPdfType(String pdfType) {
this.pdfType = pdfType;
}
}
I lod that entity for a DAO, put it in a process variable, and trying to acces to it during an other task, and I've got an Exception when I'm trying to access to any property :
[ERROR] org.hibernate.LazyInitializationException 42 - could not initialize proxy - no Session

at mypackage.process.vacancy.VacancyProcessTest.testProcess(VacancyProcessTest.java:100)
Any idea to solve that issue ?
