title: extjs: How to l set value for combobox when loading
body: <ol>
  <li><p>I am looking for a <strong><em>load</em></strong> listener, that when the combobox is up, <strong><em>load</em></strong> will be called and preform an ajax to the server to take the correct display value for the combobox.
  But, load function is never called.. how can i fix it ?</p></li>
  <li><p>I want to display a text before the combobox, so i added the attribute <code>fieldLabel: 'Save logs to:'</code>. But the text is not displayed.</p></li>
  </ol>
  
  <p>Thx,
  Yoni</p>
  
  <pre><code>this.log_save_combo = new Ext.form.ComboBox
      ({
          store: ['Device', 'USB1', 'USB2']
          , id: 'cplogs_log_save_combo'
          , name: 'cplogs_log_save_combo'
          , triggerAction:'all'
          , fieldLabel: 'Save logs to:'
          , editable: false
          //, value: "Device"
          , listeners: {
                  'load': function(){
                          alert("in load function");
                }
      });
  </code></pre>
