Help using app_standard.event(when-tab-page-changed')

Question

Hello ,
I need to create a form with the following requirements . There is one content canvas which contains a tabbed canvas and on this there are two stacked canvases .
The problem is that when I compile my form and ftp to oebs , I cannot view the tab pages on the canvas .
I see only my the fields displayed in the first tab page without the 'tab pages'.
How do I solve this issue please ?
My when-page-page-trigger contains the following :
BEGIN
     APP_STANDARD.EVENT('WHEN-TAB-PAGE-CHANGED');
if name_in('system.cursor_block') = 'XX_ERROR_MANAGEMENT' then
if not form_success then
-- Revert tab to prior value and exit
set_canvas_property('CAN_INT',topmost_tab_page,name_in('system.tab_previous_page'));
return;
end if;
-- Move to first item on each tab
if target_canvas_name = 'CAN_INT' then
     SHOW_VIEW('CAN_ONG1');
go_item('XX_ERROR_MANAGEMENT.INTERFACE_TYPE');
else
show_view(target_canvas_name);
end if;
END IF;
END;
Any help will be much appreciated . Thanks .
