title: Struts2 dynamic parameter name in redirect-action
body: <p>I'm successfully using a redirect-action for one of my struts2 mapping files as follows:</p>
  
  <pre><code>&lt;action name="setAsCurrentCart" class="com.fmp.MyAction"&gt;
    &lt;result name="success" type="redirect-action"&gt;
      &lt;param name="actionName"&gt;myOtherAction&lt;/param&gt;
      &lt;param name="foo"&gt;${foo}&lt;/param&gt;
    &lt;/result&gt;
    &lt;interceptor-ref name="defaultComponentStack"/&gt;
  &lt;/action&gt;
  </code></pre>
  
  <p>Here's what I want to do though:</p>
  
  <pre><code>&lt;action name="setAsCurrentCart" class="com.fmp.MyAction"&gt;
    &lt;result name="success" type="redirect-action"&gt;
      &lt;param name="actionName"&gt;myOtherAction&lt;/param&gt;
      &lt;param name="${dynamicParameterName}"&gt;${dynamicParameterValue}&lt;/param&gt;
    &lt;/result&gt;
    &lt;interceptor-ref name="defaultComponentStack"/&gt;
  &lt;/action&gt;
  </code></pre>
  
  <p>In other words, I want the name of the parameter that I'm passing to be dynamic.  Does anyone know if this is possible?</p>
