Question

I am using Primefaces 3.0. I have a datatable with selectionMode single as shown below:

 <p:dataTable  id="paySumm" var="PSummRow" 
 value="#{beanPySummary.PySummariesModel}" 
 selection="#{beanPySummary.selectedPySummary}" selectionMode="single" paginator="true" 
 rows="15" paginatorTemplate="{RowsPerPageDropdown}  {FirstPageLink} {PreviousPageLink} 
 {CurrentPageReport} {NextPageLink}"  rowsPerPageTemplate="10,15,25,35" >

 <p:ajax event="rowSelect" listener="#{beanPySummary.onRowSelect}" />

I have some business logic in the method onRowSelect and then I navigate to another page.

public String onRowSelect(SelectEvent event) {
   ......
   ConfigurableNavigationHandler configurableNavigationHandler =
   getCurrentInstance().getApplication().getNavigationHandler(); 
   configurableNavigationHandler.performNavigation("MoreDetail?faces-redirect=true
   return  "";

I have some data that I would like to pass as parameters to MoreDeatils with includeViewParam. I can define those as f:ViewParam in MoreDeatils.xhtml. I am not sure if I need to use ManagedProperty annotation and at the same time define those params as hidden fields on my datatable page. Here I need advise and directions.

Thanks,
Peter

You can just send a redirect by ExternalContext#redirect(). The data which you’d like to send along needs to be set in the query string of the URL.

public void onRowSelect(SelectEvent event) throws IOException {
    String field1 = URLEncoder.encode(this.field1, "UTF-8");
    String field2 = URLEncoder.encode(this.field2, "UTF-8");
    String field3 = URLEncoder.encode(this.field3, "UTF-8");
    String url = "MoreDetail.xhtml?field1=" + field1 + "&field2=" + field2 + "&field3=" + field3;
    FacesContext.getCurrentInstance().getExternalContext().redirect(url);
}

Please note that (ajax) action listener methods are supposed to return void.
