Actually, I'm using four different @DataModel. Three of these have their own @DataModelSelection.

The page is composed of a page with a table (uses mainListItems). and a small list of selected items (populated by selectedListItems).

The page uses a facelet template, which contains a menu (populated by leftMenuList), and a special list (populated by oPoolItems).

The main table looks like this (i'm not sending complete xhtml listings for all 6 files yet):

<h:dataTable value="#{mainListItems}" var="listItem" id="mooxTable">
 <h:column>
 <h:outputText value="(#{listItem.localItem.title}) "/>
 </h:column>

 <!-- Open -->
 <h:column>
 <s:link action="#{mainBean.selectListItem}" value="S:Open"/>
 </h:column>

</h:dataTable>

@Name("mainBean")
@Scope(ScopeType.SESSION)
public class MainBean extends AbstractSeamBean {

 /* REMOVED: Import of referenced beans */

 /**
 * This list contains the select list items.
 */
 @DataModel
 private List<ContentListItem> selectedListItems = new ArrayList<ContentListItem>();

 /**
 * This is the current content of the main content area.
 */
 @Out(required = false)
 private ContentListItem currentMainObject = new ContentListItem(0, new MooxMock("Nothing"));

 public boolean isCurrentList() {
 return (null != currentMainObject && currentMainObject.getLocalItem() instanceof MooxList);
 }


 /**
 * This is the data model for the left menu.
 */
 @DataModel
 private List<ContentListItem> leftMenuList;

 @DataModelSelection("leftMenuList")
 private ContentListItem selectedLeftMenItem;

 @Factory("leftMenuList")
 public void loadMenu() {
 /* REMOVED: "leftMenuList" initialization */
 }

 public String selectLeftMenuItem() {
 return setCurrentObject(selectedLeftMenItem);
 }


 /**
 * This is the data model for the list view.
 */
 @DataModel
 @SuppressWarnings({"MismatchedQueryAndUpdateOfCollection"})
 private List<ContentListItem> mainListItems = new ArrayList<ContentListItem>();

 @DataModelSelection("mainListItems")
 private ContentListItem selectedListItem;

 @Factory("mainListItems")
 public void updateListItems() {
 /* REMOVED: "mainListItems" initialization */
 }

 /**
 * Action method used when selecting a list view item.
 *
 * @return Navigation.
 */
 public String selectListItem() {
 return setCurrentObject(selectedListItem);
 }

 /**
 * Sets a list item as the new object for the main area.
 *
 * @param newObject The new object to show in main area.
 * @return Navigation.
 */
 public String setCurrentObject(ContentListItem newObject) {
 log.debug("** MainBean - setCurrentObject: #0", currentMainObject);

 currentMainObject = newObject;
 updateListItems();

 return (isCurrentList() ? "listSelected" : "objectSelected");
 }


 /**
 * O-pool.
 */
 @DataModel
 private List<ContentListItem> oPoolItems;

 @DataModelSelection("oPoolItems")
 private ContentListItem selectedOpoolItem;

 @Factory("oPoolItems")
 public void updateOPoolItems() {
 /* REMOVED: "oPoolItems" initialization */
 }

 /**
 * Action method used when selecting an O-pool item.
 *
 * @return Navigation.
 */
 public String selectOpoolItem() {
 return setCurrentObject(selectedOpoolItem);
 }

}

That's it!! I'm reloading the list when entering detail view. Of cours I can't go back to thelist again. Completely logical now when I see it.

I removed the updateListItems() call and now it works!!

You're my hero!
