Thank you, Jacob. Following are my code snippets:pages.xml
  | <page view-id="*">
  | 	<navigation>
  | 		<rule if-outcome="emailList">
  | 			<redirect view-id="/emails.xhtml"/>
  | 		</rule>
  | 		<rule if-outcome="phoneList">
  | 			<redirect view-id="/phones.xhtml"/>
  | 		</rule>
  | 		....
  | 
  | sidebar.xhtml
  | 	<div>
  | 		<ice:commandLink value="Contact Emails"
  | 				action="#{contactServicer.retrieveEmails}"/>
  | 	</div>
  | 
  | 	<div>
  | 		<ice:commandLink value="Contact Phones"
  | 				action="#{contactServicer.retrievePhones}"/>
  | 	</div>
  | 	...
  | 
  | emails.xhtml
  | 	<ice:panelSeries style="clear: both;"
  | 			value="#{emailList}"
  | 			var="email" rendered="#{!empty emailList}">
  | 		<div class="row">
  | 			<ice:outputText value="#{email.emailAddress}"/>
  | 		</div>
  | 		....
  | 
  | phones.xhtml
  | 	<ice:panelSeries style="clear: both;"
  | 			value="#{phoneList}"
  | 			var="phone" rendered="#{!empty phoneList}">
  | 		<div class="row">
  | 			<ice:outputText value="#{phone.phoneNumber}"/>
  | 		</div>
  | 		....
  | 
  | @Name("contactServicer")
  | @Stateless
  | @Scope(ScopeType.STATELESS)
  | public class ContactServicerBean implements ContactServicer {
  | 
  | 
  | 	@Out(required=false, scope=ScopeType.CONVERSATION) //EVENT and PAGE don't work
  | 	private List<Email> emailList;
  | 
  | 	@Out(required=false, scope=ScopeType.CONVERSATION) //EVENT and PAGE don't work
  | 	private List<Phone> phoneList;
  | 
  | 
  | 	public String retrieveEmails() {
  | 		emailList = em.createNamedQuery("...").getResultList();
  | 		return "emailList"
  | 	}
  | 
  | 	public String retrievePhones() {
  | 		phoneList = em.createNamedQuery("...").getResultList();
  | 		return "phoneList";
  | 	}
  | 
  | 	....
  | }

Otherwise, the temporary conversation will be destroyed and your data is gone on the next request.I don't know which pattern is good for enterprise project based on my codes above. Seam wiki pagination sample is using Stateless bean + Event outjection, but I couldn't make this work.
