Witam. Napotkałem na błąd w mojej aplikacji i zupełnie nie wiem jak sobie z nim poradzić. Mam stronę, która wyświetla listę wizyt:
<p:dataTable id="table" styleClass="tableHistory" value="#{patientCardMB.history}" var="history" paginator="true" rows="15" rowKey="#{history.id}" selection="#{patientCardMB.patientCard}" selectionMode="single" >
<f:facet name="header">
Historia
</f:facet>
<p:column headerText="#{msg.date}">
<h:outputText id="historyText" value="#{history.dateVisit}"/>
</p:column>
<p:ajax event="rowSelect" listener="#{tableBean.onRowSelect()}" update=":form:table" />
<f:facet name="footer">
<p:commandButton id="viewButton" value="#{msg.info}" icon="ui-icon-search"
update=":form:display" oncomplete="userDialog.show()" disabled="#{tableBean.flag}"/>
<p:commandButton action="#{patientCardMB.createStart()}" value="#{msg.add}" icon="ui-icon-plus" />
<p:commandButton action="#{patientCardMB.editStart()}" value="#{msg.edit}" disabled="#{tableBean.flag}" ajax="false" icon="ui-icon-pencil"/>
<p:commandButton value="#{msg.delete}" onclick="confirmation.show()" type="button" disabled="#{tableBean.flag}" icon="ui-icon-close"/>
<p:confirmDialog id="confirmDialog" message="Jesteś pewien, że chcesz usunąć wybrany wpis?"
header="Potwierdzenie usunięcia" severity="alert" widgetVar="confirmation">
<p:commandButton id="confirm" value="Tak" oncomplete="confirmation.hide()"
action="#{patientCardMB.delete()}" />
<p:commandButton id="decline" value="Nie" onclick="confirmation.hide()" type="button" />
</p:confirmDialog>
</f:facet>
</p:dataTable>
Po zaznaczeniu wiersza do usunięcia wykonywana jest metoda delete:
public String delete() {
System.out.println(patientCard);
try {
patientCardDao.delete(patientCard);
} catch (EJBException e) {
sendErrorMessageToUser("Błąd usuwania wpisu");
}
sendInfoMessageToUser("Wpis usunięty");
return "delete";
}
patientCardDAo.delete:
@Override
public void delete(PatientCard patientCard) {
PatientCard toRemoved = em.merge(patientCard);
em.remove(toRemoved);
}
Klasa encyjna patientCard:
public class PatientCard implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
private Integer id;
@Basic(optional = false)
@NotNull
@Column(name = "dateVisit")
@Temporal(TemporalType.TIMESTAMP)
private Date dateVisit;
@Size(max = 4000)
@Column(name = "diagnosis")
private String diagnosis;
@Size(max = 250)
@Column(name = "medications")
private String medications;
@JoinColumn(name = "patient_id", referencedColumnName = "id")
@ManyToOne(optional = false)
private User patientId;
@JoinColumn(name = "doctor_id", referencedColumnName = "id")
@ManyToOne(optional = false)
private User doctorId;
Jednak w momencie próby usunięcia dostaję następujący błąd:

Zupełnie nie wiem czemu się tak dzieje? Może ktoś pomóc? Wykonywałem już operacje usuwania na podobnych klasach i wszytsko działało.
