Im using primefaces version 3.1.1, Mojarra 2.1.3, Netbeans 7.0.1, Glassfish Server 3.1.
My test application is using a facelet template with top, left, content, right and bottom layout with raw divs and css. After user logs in with container managed jdbcrealm, they will be presented with the main index.html which use the said template.
I put a navigation menu on the left panel which will subsequently update center panel content with ajax upon clicking menuitem. The center panel will be updated dynamically in <ui:include> by using sessionScoped NavigationBean.
In one of the page clientList.xhtml, I put a <p:dataTable> with a button to view the detail by popping up a <p:dialog>. Im using a viewCoped bean to hold the data list displayed on the dataTable.
The problem is, when I click on the button to select a row in the last colum of every row, the dialog does not appear at all, and my p:ajaxStatus gif image kept on rolling unendingly. When I debug the program with netbeans, I notice the constructor is called again and the previous instance is gone after clicking the button.
This is my index.xhtml using facelets template.

This is the clientList.xhtml page which is displayed in the center panel of my index.xhtml upon clicking a link on the menu in the left panel.

This is my Backing Bean.
public class SaClientController implements Serializable {
@EJB
private SaClientFacade saClientFacade;
private SaClient selectedSaClient;
private LazyDataModel<SaClient> lazyModel;
private List<SaClient> saclients;

This is the LazyModelImp class

//rowCount
int dataSize = data.size();
this.setRowCount(dataSize);
//paginate
if (dataSize > pageSize) {

}
//sort

//return data;
}
}
I've already disabled the partial state saving in web.xml.

The backingBean is reinitialized the first time I click on the view detail commandButton in the last column of the dataTable in clienList.xhtml. And the dialog does not display at all. But after pressing F5. The dialog can be displayed but without any content, the only thing displayed in the dialog is the label outputText but not the bean values, they are empty. Sorry for newbie question. I will be extremely glad if anyone could advise what im doing is wrong, and maybe a little advise on the navigation and whether my strategy of displaying everything in index.xhtml (so I only have 1 view id all the time which is index.xhtml, right?) is right.
