title: Is it posible to use request parameters in spring webflow view?
body: <p>I am newbie in Spring Webflow and I am migrating and old Java MVC application to Spring MVC + WebFlow.</p>
  
  <p>Navigation in our old application worked with URLs like this <code>/MyServlet?action=myAction&amp;status=1</code> and we need to mantain them in the new application. So we have create a Controller that controls all requests to MyServlet with</p>
  
  <pre><code>@RequestMapping(value="/MyServlet", method = {RequestMethod.POST, RequestMethod.GET})
  </code></pre>
  
  <p>In this controller we have old servlet code who execute actions. This solution permit us use old code under Spring control.</p>
  
  <p>Now we want to use WebFlow, but all views are expressed with URLs mention above and when I try to create a flow, it seems to be invalid. I have the following error: </p>
  
  <blockquote>
    <p>The reference to entity "action" must end with the ';' delimiter</p>
  </blockquote>
  
  <p>This is my XML flow file:</p>
  
  <pre><code>&lt;view-state id="idIn" view="/MyServlet?action=myAction&amp;status=1"&gt;
      &lt;transition on="list" to="idList" /&gt;
  &lt;/view-state&gt;
  
  &lt;view-state id="idList" view="/MyServlet?action=myAction&amp;status=2"&gt;
      &lt;transition on="new" to="idNew" /&gt;
  &lt;/view-state&gt;
  
  &lt;view-state id="idNew" view="/MyServlet?action=myAction&amp;status=3"&gt;
      &lt;transition on="out" to="idOut" /&gt;
  &lt;/view-state&gt;
  
  &lt;end-state id="idOut" view="/MyServlet"&gt;
  &lt;/end-state&gt;
  </code></pre>
  
  <p>Is it possible to use URL with parameters in Spring WebFLow? How could I do it?</p>
  
  <p>Thanks a lot in advance.</p>
