JSF Primefaces commandButton

我試圖在頁面中創建一個命令按鈕，但沒有得到操作方法的響應。JSF Primefaces commandButton

PS：新中PrimeFaces

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()); 
    } 
}

在inputText值不能爲空

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

相反，你必須與一定財產託管bean實例：

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

注意

您必須在ManagedBean中創建屬性。

看看在Primeface show cases，約inputText

我認爲它這個，這是一個註冊頁面，所以我有這個值來接收來自用戶輸入的數據？ – AgamenonD2

是的，這是正確的@ AgamenonD2 –

tks，解決了這個問題。 – AgamenonD2
