title: dropdown menu "Conversion Error setting value '' for 'null Converter'"
body: <p>So i am using seam to try to make a dropdown menu to add a delivery to a database. I'm using a drop down menu to select which employee from the database is doing the delivery. The menu loads all the employees in the database just fine but when I select one and click add, I get the error "Conversion Error setting value '(hash for employee)' for 'null Converter'.</p>
  
  <p>here's the code for the dropdown menu:</p>
  
  <pre><code>&lt;my:dropdown label="Employee ID" id="emp" value="#{deliveryPort.emp}" required="false"&gt;
                      &lt;f:selectItem itemValue="#{null}" itemLabel="Selct One"/&gt;
                      &lt;s:selectItems value="#{deliveryPort.empList}" var="emp" label="#   {emp.employeeId} #{ emp.nameFirst}"/&gt; 
                 &lt;/my:dropdown&gt;
  </code></pre>
  
  <p>Any help would be greatly appreciated. Thank you</p>
