title: drupal why MENU_NORMAL_ITEM can't work
body: <p>i haved written a simple module to practice the hook_menu. but it doesn't work. what's wrong with my code. 
        
  
  <pre><code>   function mymenu1_menu(){
    $item = array();
  
    $item['mymenu/menu'] = array (
     'description' =&gt;'test1',
     'page callback' =&gt; 'mymenu_test_access',
     'access callback' =&gt; 'mymenu_is_test_access',
     'type' =&gt;MENU_NORMAL_ITEM,    
     );
     return $item;
  
    }
  
    function mymenu_test_access(){
    $output = 'you're logged';
    return $output;
    }
  
    function mymenu_is_test_access(){
      return $GLOBALS['user']-&gt;uid &gt;0 ;
      }
  </code></pre>
  
  <p>my module name is mymenu1, the module info file is right, the cache is cleared. but in the navigation part, i can't see the menu that i created. thank you.</p>
