EntityNotFoundException: deleted entity passed to persist

Question

I try to delete one row in my table:

My page:

        <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>

I do a method patientCardMB.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);
}

Entity 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;

When i try delete i have this error:

I don't now why i have this error. Earlier I did delete a similar entity, and all work.

Answer 1

I think you're missing process and update attribute in

 <p:commandButton id="confirm" value="Tak" oncomplete="confirmation.hide()"
                                 action="#{patientCardMB.delete()}" process="@parent" update="@form" />
