This layout allows to render several tiles in a tabs fashion. Such tabs can be nested: a tab level can contain nested tabs. Each tabs must be declared with a different parameter name. Implementation store each tabs selection index in the session context. The unique id for the session attribut is compute from the url and the tabs selection parameter. [todo] Improve the computation of unique id. @param tabList A list of available tabs. We use MenuItem to carry data (name, body, icon, ...) @param selectedIndex Index of default selected tab @param parameterName Name of parameter carrying selected info in http request. --%> <%-- Use tiles attributes, and declare them as page java variable. These attribute must be passed to the tile. --%> <% String selectedColor="#98ABC7"; String notSelectedColor="#C0C0C0"; int index = 0; // Loop index int selectedIndex = 0; // Check if selected come from request parameter try { selectedIndex = Integer.parseInt(selectedIndexStr); // Try to retrieve from http parameter, or previous storage // Need to use a more unique id for storage name String paramValue = request.getParameter( parameterName ); if( paramValue == null ) { selectedIndex = ((Integer)(session.getAttribute( request.getRequestURI() + parameterName ))).intValue(); } else selectedIndex = Integer.parseInt(paramValue); } catch( java.lang.NumberFormatException ex ) { // do nothing } catch( java.lang.NullPointerException ex ) { // do nothing } // Check selectedIndex bounds if( selectedIndex < 0 || selectedIndex >= tabList.size() ) selectedIndex = 0; String selectedBody = ((org.apache.struts.tiles.beans.MenuItem)tabList.get(selectedIndex)).getLink(); // Selected body // Store selected index for future references session.setAttribute( request.getRequestURI() + parameterName , new Integer(selectedIndex) ); %> <%-- Draw tabs --%> <%-- Draw body --%>
