在视图中找到重复的组件ID

我收到一个错误,例如已在树表列标签中的视图中找到组件ID组件,其中id = col1.我有两个Managed Beans用于这个单个xhtml文件,并且都是会话作用域.

可以为Int数组赋予数组中所有数字的值吗？

int[] high = {2,3,4,5,6};

数组是否可以给出-1的恒定值？清除{2,3,4,5,6}都等于-1.

我是Java Server Faces的新手.我正在做一个简单的登录jsf应用程序,它有layout.xhtml,login.xhtml,loginbean.java,changepassword.xhtml,changepasswordbean.java.登录功能工作正常,但更改密码功能导致一些问题,我找不到错误的原因.在changepassword.xhtml页面中单击"清除按钮"时出现错误.如果我单击changepassword按钮,则出现Null指针异常,因为我试图从另一个loginbean获取值(companyid)到changepasswordbean.在浏览器中单击后退按钮然后选择changepassword菜单我收到一个错误,如父不是null,但此组件不相关.有时菜单不会显示.我不知道这是什么问题,所以在这里有任何帮助.

LoginBean.java

    import javax.faces.bean.ManagedBean;
    import javax.faces.bean.ManagedProperty;
    import javax.faces.bean.SessionScoped;
    import java.io.Serializable;
    import javax.faces.application.FacesMessage;
     import javax.faces.context.FacesContext;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;

     @ManagedBean
    @SessionScoped
      public class LoginBean implements Serializable 
    {
     Logger log;

      @ManagedProperty(value = "loginBean")

      public boolean isLoggedin;
     public String username;
       public String password;    
     public String companyid;  
     public boolean notloggedin;   

    @ManagedProperty(value = "#{tabMenu}")
    private TabMenu tabMenu;

    public LoginBean() 
      {
          log=LoggerFactory.getLogger(LoginBean.class);
           }

     public void clear()
        {        
     setUsername(null);
     setPassword(null);
     setCompanyId(null);
    }

      public String login()
     {       
    setIsLoggedin(true);
            setNotLoggedIn(false);
