title: Ext JS 4.2 paging combo - how to skip to page
body: <p>I have a Combo such as:</p>
  
  <pre><code>{
          xtype : 'combo',
          anchor : '70%',
          id : 'companyCombo',
          fieldLabel : 'Company',
          name : 'COMPANY_ID',
          store: companyStore,
          pageSize: 25,
          displayField : 'COMPANYNAME',
          valueField : 'COMPANY_ID',
          typeAhead : true,
          queryMode : 'local',
          forceSelection : true,
          allowBlank : false,
          editable : true
  },
  </code></pre>
  
  <p>When using a paging Combo Box with Ajax data, I am advised to first determine (via Ajax) which 'page' the current item is on, and then set the Combo's page to that via:</p>
  
  <pre><code>pagingtoolbar.move(pageNumber)
  </code></pre>
  
  <p>The problem is, I'm not sure how to get a reference to <code>pagingtoolbar</code> for the Combo.  It doesn't seem to correspond to any of the member fields of the object returned via <code>Ext.getCmp('companyCombo')</code>... </p>
