title: Problem in returning values from javascript function to flex
body: <p>In the attached flex code, I am trying to call a javascript function in its HTML wrapper.
  The example is also live at :
  <a href="http://www.cse.epicenterlabs.com/mbm/ajax_api.html" rel="nofollow noreferrer">http://www.cse.epicenterlabs.com/mbm/ajax_api.html</a>
  The problem I am facing is, that I have to click the button twice
  to get the desired output. Seems like there is some delay in setting the
  "output" variable. How could I get the output from the javascript function in one click?</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

          &lt;![CDATA[
                  import mx.rpc.events.ResultEvent;

       public function callWrapper():void {
          var s:String;
          if (ExternalInterface.available) {
             var wrapperFunction:String = "initialize";
             s = ExternalInterface.call(wrapperFunction,text1.text);
             text1.text = s;
  
          } else {
             s = "Wrapper not available";
          }
          trace(s);
