Java Primefaces拾取列表数据未从源传输到目标

Java Primefaces拾取列表数据未从源传输到目标,java,xhtml,primefaces,Java,Xhtml,Primefaces,我在JavaWeb应用程序中使用了一个选择列表。但当我测试它时,值并没有移动到目标列表。我单独做了这件事,效果很好。然后我复制了代码并将其粘贴到我的原始页面,当它不工作时,我不明白为什么需要帮助 这是我的xhtml工作代码: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:p="http://primefaces.org/ui" xmlns:f

基本挑选名单

第一个选择列表工作,第二个选择列表在“编辑资源”选项卡中出现问题

这是java文件:

    private List<String>addResourceIpSource = new ArrayList<String>();
    private List<String>addResourceIpTarget = new ArrayList<String>();
    private DualListModel<String> AddResorcesipList;
        public void setIpSource() throws SQLException, ClassNotFoundException{



    String q = "SELECT * FROM ipp.resource;";
        ResultSet result = DB_Access.getData(q);

        while(result.next()){
            resourceRow r = new resourceRow();
            r.setIpAddress(result.getString(1));
            addResourceIpSource.add(result.getString(1)); 

        }
  //ipSource.add("select resource for perticuler instance.."); 
    // ipList = new DualListModel<String>(ipSource, ipTarget);
     AddResorcesipList = new DualListModel<String>(addResourceIpSource, addResourceIpTarget);
}
private-ListaddResourceIpSource=new-ArrayList();
private ListaddResourceIpTarget=新的ArrayList();
私有DualListModel AddResorcesipList;
public void setIpSource()引发SQLException,ClassNotFoundException{
String q=“从ipp.resource中选择*”;
ResultSet result=DB_Access.getData(q);
while(result.next()){
resourceRow r=新的resourceRow();
r、 setIpAddress(result.getString(1));
addResourceIpSource.add(result.getString(1));
}
//add(“为perticular实例选择资源…”);
//ipList=新的DualListModel(ipSource、ipTarget);
AddResorcesipList=新的DualListModel(addResourceIpSource,addResourceIpTarget);
}

函数是在类构造函数中调用的…

我以前也遇到过类似的问题。下面的使用一开始不会被警告,但它可能会使primeface逻辑混乱。不要像下面这样使用

<h:form>
<h:form></h:form>
</h:form>


这里有嵌套表单。您不能嵌套不可接受的
表单
标记。抱歉,我没有足够的声誉更新一点。。。。添加了一个下拉列表(在菜单上选择),并在使用ajax从下拉列表中选择值时设置加载源
    private List<String>addResourceIpSource = new ArrayList<String>();
    private List<String>addResourceIpTarget = new ArrayList<String>();
    private DualListModel<String> AddResorcesipList;
        public void setIpSource() throws SQLException, ClassNotFoundException{



    String q = "SELECT * FROM ipp.resource;";
        ResultSet result = DB_Access.getData(q);

        while(result.next()){
            resourceRow r = new resourceRow();
            r.setIpAddress(result.getString(1));
            addResourceIpSource.add(result.getString(1)); 

        }
  //ipSource.add("select resource for perticuler instance.."); 
    // ipList = new DualListModel<String>(ipSource, ipTarget);
     AddResorcesipList = new DualListModel<String>(addResourceIpSource, addResourceIpTarget);
}
