title: Extjs Combobox: forceSelection false on combobox not working
body: <p>I have created a combobox and attached a array to store. What i wanted is that use can select from the list OR can type custom text as well. I searched that can be achieved through forceSelection = false, i read the docs that and found out that forceSelection is by default false and as i'm using sencha architect so i can't explicitly set the config. So below is the config which i have done. But as soon as i press tab or enter the typed text in combobox no longer exist.</p>
  
  <pre><code>{
  xtype: 'fieldcontainer',                                    
  id: 'internetmessager',
  autoDestroy: false,
  layout: {
      align: 'stretch',
      type: 'hbox'
  },
  items: [
      {
          xtype: 'combobox',
          flex: 1,
          margin: '0 10 0 0',
          name: 'label',
          autoSelect: false,
          queryMode: 'local',
          store: [
              'Home',
              'Work',
              'Personal'
          ],
          typeAhead: true
      },
      {
          xtype: 'textfield',
          flex: 2,
          name: 'value',
          emptyText: 'IM'
      }
  ]
  }
  </code></pre>
