更改你的託管bean刪除方法是這樣的;

public void deletePersonel(int personel_id){ 
     Personel personel=(Personel)personelservice.getPersonelId(personel_id); 
     getPersonelservice().deletePersonel(personel); 
    }

並且還改變你的xhtml喜歡這個;

<p:commandButton icon="ui-icon-close" title="حذف" 
        actionListener="#{personelMB.deletePersonel(personel.personel_id)}" />

添加刷新方法到您的託管bean喜歡這個;

public String deleteAction(Personel personel) { 
    personelList.remove(personel); 
    return null; 
    }

並編輯你的p：commandButton喜歡這個;

<p:commandButton icon="ui-icon-close" title="حذف" 
        actionListener="#{personelMB.deletePersonel(personel.personel_id)" action="#{personelMB.delectAction(personel)}"/>

@sami檢查我的編輯帖子。 – 2012-08-06 08:00:49

我有這個錯誤：/personel.xhtml @ 96,139 action =「＃{personelMB.deleteAction（personel）}」：找不到方法：[email protected]（model.Personel） – samira 2012-08-06 08:15:33
