EntityHome request parameter

Hi- I am having trouble receiving a different request parameter other than what is generated by seam-gen..

I have the following code in the XXXHome.. eventId comes in just fine but the parentId is null..

@RequestParameter
Long eventId = null;

@RequestParameter
Long parentId;

Here is the XXXlist. xhtml fragment that calls that code..

<h:column>
<f:facet name="header">Title</f:facet>
<s:link id="event" value="#{event.title}" view="/event.xhtml">
<f:param name="eventId" value="#{event.id}"/>
</s:link>
</h:column>
<h:column>
<f:facet name="header"></f:facet>
<s:link id="event" value="Add Sub Event" view="/event.xhtml">
<f:param name="parentId" value="#{event.id}"/>
</s:link>
</h:column>

Above, first link works and eventId param is passed but the parentId param is not passed..

So the question is how can I pass the event.id as a request parameter with a different name into XXXHome?

Thanks.

I was wrong in saying eventId param is passed.. It was passed initially during the creation of the instance but not when it was being saved.. I missed this little detail at 4am..

I have found that the following is a solution, as documented in chapter 10.2

@Factory("event")
public Event initEvent() {
return getInstance();
}

protected Event createInstance() {
Event event = new Event();
Event parent = getEntityManager().find(Event.class, Long.valueOf(parentId));
event.setParent(parent);
return event;
}
