title: How to load or set value in tagfield
body: <p>I am using a tagfield as a widget column. I am selecting few values from drop down and then saving it. Again when I open I wanted my selected value should be present there in tagfield. It is only coming only after tagfield getting focused.</p>
  
  <p>What I am trying here is, My Code : </p>
  
  <pre><code> var SValue = XML.getAttribute('value');
  
  if(filterType.xtype == "tagfield"){
          filterType.setValue(SValue); // This is not working
          filterField.inputEl.set({'placeholder':SValue}); // This is working but not correct way to do.
      }
  </code></pre>
  
  <p>I used placeholder it somewhat showing values but this is not correct what I want. Can anyone suggest me what I can do here. If it is getting automatically focused then also there is chance to work. </p>
  
  <p>Note :  In another word its like how to load or set the value to tagfield by reading particular attribute from XML.</p>
