Subject: Uncaught exception when tried to return a StreamResponse

Hi Guys,

        I want to export data in excel sheet, so I made a page class as the 
following without a template file(.tml)

public class ExportExcel {
        .
        .
        .
        
        StreamResponse OnActivate(){
                List<User> users = userManager.getAllActiveUsers();        // 
break point here never got hit
                return export(users);
        }
        
        public StreamResponse export(List<List<String>> rows) {
                // some logic to export the data in .xls
        }
}

And this is the error I got:
Page export/Excel did not generate any markup when rendered. This could be 
because its template file could not be located, or because a render phase 
method in the page prevented rendering.


And I am using this page link.
<t:pagelink t:page="export/excel"
                      title="message:export-label"/>

any idea what is the problem ?

Thanks in Advance,
Amr Hassanin
