Question

我试图在页面中创建一个命令按钮，但没有得到动作方法的响应。

PS：PrimeFaces中的新功能

package br.com.copagaz.inova.mobile.web.mb.frota;

import java.io.Serializable;

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

@SessionScoped
@ManagedBean(name = "CadFrota", eager = false)
public class CadFrota implements Serializable {

    private static final long serialVersionUID = -5734393292489385792L;

    public void teste(ActionEvent actionEvent){
       System.out.println("teste: " + actionEvent.toString());
    }
}

Answer 1

inputText中的值不应为空

<p:inputText id="i10" value="" />

相反，您必须与托管bean中的属性相关，例如：

<p:inputText id="i10" value="#{cadFrota.attribute}" />

注意

您必须在ManagedBean中创建属性。

查看Primeface show cases，关于inputText

JSF Primefaces commandButton
