title: How do I pass struts2 <s:select multiple="true"> with a Map
body: <p>I have an bean placed on my action Event.java, the action is Called ManageEvents.  I would like the user to be able to add to a struts2 multiple select form field and create a list or map of items (in this case Map where the data would be . </p>
  
  <pre><code>&lt;struts2:select name="event.dj_map" label="Add DJs To Your Event" list="event.dj_map" listsize="5" multiple="true" headerKey="headerKey" required="true" headerValue="--- Please Select ---"&gt;
  </code></pre>
  
  <p>So ultimately I would like to know how to pass a mult. select field (e.g. Events.dj_map) as a map of name,value pairs to an object (e.g. Event.java) set on the action (e.g. ManageEvents.java).</p>
