Question

当我点击按钮New <p:commandButton actionListener="#{ecritureCtrl.newLine}" value="New" update="dataTableSaisiePiece" oncomplete="addRowOnComplete()" ajax="true"/>时，只有第一次点击时，我的dataTable会添加一个新行，并刷新页面。除第一个之外的几个派系都没有刷新dataTable。因此，要查看我新添加的行，我使用F5键刷新页面。当然我的update="dataTableSaisiePiece"不起作用或只起作用而不是第一次点击。

这是我的页面home.xhtml：

我的ManagedBean：

    @SessionScoped

    private List<Avant> lignes = new ArrayList<Avant>();
    Avant unUser;

    private String description;
    private Date date;
    private String code;
        public EcritureCtrl() {
            lignes.add(new Avant());
         }

        public void newLine(ActionEvent actionEvent){
            lignes.add(new Avant());            
        }

    }

你能帮帮我吗？提前谢谢。

这似乎对我有用

import java.io.Serializable;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.event.ActionEvent;

@ManagedBean
@SessionScoped
public class EcritureCtrl implements Serializable {
    private static final long   serialVersionUID    = 1L;
    private String              code;
    private Date                date;

    private String              description;
    private List<Avant>         lignes              = new ArrayList<Avant>();
    private Avant               unUser;

    public String getCode() {
        return this.code;
    }

    public Date getDate() {
        return this.date;
    }

    public String getDescription() {
        return this.description;
    }

    public List<Avant> getLignes() {
        return this.lignes;
    }

    public Avant getUnUser() {
        return this.unUser;
    }

    @PostConstruct
    private void init(){
        this.lignes.add(new Avant());
    }

    public void newLine(ActionEvent actionEvent) {
        this.lignes.add(new Avant());
    }

    public void setCode(String code) {
        this.code = code;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public void setLignes(List<Avant> lignes) {
        this.lignes = lignes;
    }

    public void setUnUser(Avant unUser) {
        this.unUser = unUser;
    }

}
