I want to convert my web application into a portlet on liferay.

My welcome page is well rendered into the portlet frame, but I have a problem when I try to call a redirect action to another

page. These pages seem to try rendering out of portlet context, and seam conversation is over.

I can't see any error, but the URL is kind of http://localhost:8080/appliweb/search/page.seam, and not liferay-style.

I just receive the message below :

17:10:50,359 INFO  [lifecycle] WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
sourceId=null[severity=(WARN 1), summary=(The conversation ended, timed out or was processing another request), detail=(The conversation ended, timed out or was processing another request)]

Here is my pages.xml:

<pages xmlns="http://jboss.com/products/seam/pages" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.0.xsd"
    no-conversation-view-id="/search/list.xhtml">

    <conversation name="ViewSearch" parameter-name="searchId" parameter-value="#{viewedSearch.id}" />

    <page view-id="/search/list.xhtml">

        <navigation from-action="#{searchView.selectSearch(s)}">
            <redirect view-id="/search/view.xhtml" />
        </navigation>
        
    </page>

</pages>

faces-config.xml

<faces-config>

    <application>
        <view-handler>com.icesoft.faces.facelets.D2DSeamFaceletViewHandler</view-handler>
    </application>

</faces-config>

list.xhtml

<ui:define name="content">
    <ice:form>
        <ice:dataTable id="searchTable" rows="10"
            columnClasses="typeColumn, titleColumn, startDateColumn, endDateColumn, leadingUnitColumn"
            rowClasses="oddRow, evenRow" sortColumn="#{searchList.sortedColumn}"
            sortAscending="#{searchList.ascending}" value="#{searchList.list}" var="s" 
            scrollHeight="310px" scrollable="true" columnWidths="24px,560px,70px,70px,200px">

            <ice:column id="typeColumn">

                <ice:graphicImage url="/img/search/image.png"
                    rendered="#{searchAxesList.getType(s) == 'OK'}"/>

                <ice:rowSelector value="false" selectionAction="#{searchView.select(s)}" />
            </ice:column>

        </ice:dataTable>
        
    </ice:form>
</ui:define>

What can I do if I want to keep the navigation and pages into the portlet ?
