Hello,
i have taken the hibernate2 example from seam 1.1.6
I added this page to the view: listHotel.xhtml
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>

| <ui:composition template="template.xhtml">
|
| <ui:define name="content">
| <div class="section"><h:form>
| <h:outputText value="No Hotel exists"
rendered="#{empty myHotels.resultList}" />
| <h:dataTable id="myHotels" var="myHotel"

| <h:column>

| <s:link view="/listHotel.xhtml"

| </s:link>
|
|
| </h:form></div>
| </ui:define>
| </ui:composition>
| </body>
| </html>
|
In gages.xml this definition is added:
<page view-id="/listHotel.xhtml">
| <param name="firstResult" value="#{myHotels.firstResult}" />
| </page>

Finally the modification of components.xml

After deploying and starting the app
pointng the browser at http://localhost:8080/jboss-seam-hibernate/listHotel.seam
results in an error screen. (/listHotel.xhtml @63,71
