title: Retaining multiple selectbox values in struts2
body: <p>Hi i have a problem with the multiple select box of struts2.</p>
  
  <pre><code>&lt;s:select name="test" id="test" multiple="true" size="2" list="testlist" theme="simple" listKey="testkey" listValue="testvalue" /&gt;
  </code></pre>
  
  <p>The select box name "test" is a field name in my entity.The list data is displaying and i can select multiple items and its stored in the database.But the problem is i could not retain the selected values while modification.But i have noticed that i can retain the value if i select only one item.Any idea?.</p>
