title: Invoke a managed bean method before render-response phase
body: <p>JSF version I using is 1.2_09. RichFaces API is 3.3.2.SR1.</p>
  
  <p>I'm using <code>&lt;rich:dataTable&gt;</code> component to render a List into a table. Let I've a manage-bean method which initialize a mange-bean property. The method will be invoked when the <code>get(int)</code> List mehtod is invoked to render the data. For instance, the method:</p>
  
  <pre><code>String orderedProperty;
  // Something else
  protected String parseOrderGetParameter(HttpServletRequest request)
      {
          String orderedProperty = "";
          Map&lt;String, String[]&gt; params = (Map&lt;String, String[]&gt;) request.getParameterMap();
          String[] value = params.get("fsp");
  
          if(value == null){
              return orderedProperty;
          }
  
          for(String s : params.get("fsp")){
              orderedProperty = orderedProperty.concat(s); 
          }
  
          String[] parts = orderedProperty.split(":");
          orderedProperty = parts[2];
          orderedProperty = orderedProperty.replaceFirst("j_id", "");
          orderedProperty = getHeaderNameById(Integer.valueOf(orderedProperty));
          return orderedProperty;
      }
  </code></pre>
  
  <p>Is there a way to invoke a maange bean method before the render-response phase?</p>
