I've been trying to use the conversation switcher in my application, but even though i start many conversations i find that the list is still empty. This is the code snippet that's on my template

 <h:form>
 <div style="clear:both;float:right;margin-top:200px;padding-right:10px">
 <h:selectOneMenu value="#{switcher.conversationIdOrOutcome}">
 <f:selectItems value="#{switcher.selectItems}"/>
 </h:selectOneMenu>

 <h:commandButton action="#{switcher.select}" value="Switch"/>
 </div>
 </h:form>

Can anybody suggest what exactly is going wrong? I copied this from the seam reference book so i thought it should work.
