My bean

Code: Select all

@ManagedBean(name= "specialityBean")
@ViewScoped
public class SpecialityBean implements Serializable
{

    @EJB
    private SpecialityEAO specialityEAO;
    private List<Speciality> specialities;
    private Speciality specialty=new Speciality();
    private Speciality selectedSpecialty;
    public SpecialityBean()
    {
    }

    @PostConstruct
    public void initialize()
    {
        this.specialities = specialityEAO.findSpecialitys();
    }

    public List<Speciality> getSpecialities()
    {
        return specialities;
    }

    public Speciality getSpecialty()
    {
        System.out.println("getSpecialty was called");
        return specialty;
    }

    public void setSpecialty(Speciality specialty)
    {
        System.out.println("setSpecialty was called");
        this.specialty=specialty;
    }

    public Speciality getSelectedSpecialty()
    {
        System.out.println("getSelectedSpecialty() was called");
        return selectedSpecialty;
    }

    public void setSelectedSpecialty(Speciality selectedSpecialty)
    {
        System.out.println("SetSelectedSpecialty:"+selectedSpecialty);
        this.selectedSpecialty = selectedSpecialty;
    }



    private String operation;
    public String action(String operation)
    {
        System.out.println("action:"+operation+"  specialty:"+specialty);
        this.operation = operation;
        return null;
    }

    public void ok(ActionEvent event)
    {

        if (this.operation.equalsIgnoreCase("add"))
        {
            System.out.println("add Specialty:"+specialty);
            return;
        }
        if (this.operation.equalsIgnoreCase("edit"))
        {
            System.out.println("edit Specialty:"+specialty);

            return;
        }
    }
}

I traced the life cycle phase, and i found that getter method instead of setter method was called at "update model value" phase.Here is the result:

before UPDATE_MODEL_VALUES: phase id - UPDATE_MODEL_VALUES 4
getSpecialty was called
getSpecialty was called
getSpecialty was called
after UPDATE_MODEL_VALUES: phase id - UPDATE_MODEL_VALUES 4

DataTable is also updating the model as you have enabled selection. You need to use partial processing feature;

Code: Select all

<p:commandButton value="ok" update="specialtyList" actionListener="#{specialityBean.ok}" oncomplete="dlg.hide()" process="display"/>

Thanks for quick answer!
I try the method you give,the datatable model is't updating. But "setSpecialty(Speciality specialty)" instead of "setSpecialty(Speciality specialty)" is called.

Code: Select all

before UPDATE_MODEL_VALUES: phase id - UPDATE_MODEL_VALUES 4
getSpecialty was called
getSpecialty was called
getSpecialty was called
after UPDATE_MODEL_VALUES: phase id - UPDATE_MODEL_VALUES 4

I think that the result shold be:

Code: Select all

before UPDATE_MODEL_VALUES: phase id - UPDATE_MODEL_VALUES 4
setSpecialty was called
setSpecialty was called
setSpecialty was called
after UPDATE_MODEL_VALUES: phase id - UPDATE_MODEL_VALUES 4
