I only get this exception when using ICEfaces inputText, however the exception ends in a SEAM class, so I think it is most pertinent in the SEAM forum first.

I converted only one of my h:inputText to ice:inputText, when I try to load the page I get the exception:

ticket.xhtml

  | <tr>
  | 	<td class="name">Name</td>
  | 	<td align="right">

  | 			<ice:inputText id="name" value="#{ticketHome.instance.name}" required="true" partialSubmit="true"/>
  | 		</s:decorate>
  | 	</td>
  | </tr>
  | ....

The TicketHome extends EntityHome and follows the conventions from the SEAM documentation.


The NPE in org.jboss.seam.util.Parameters comes from the line:

String[] array = requestParameters.get(name);

so apparently requestParameters is null, is this a bug introduced by ICEfaces even though it is in the SEAM code?
