[Building Sakai] Error on Export from Lesson tool

[Omer A Piperdi]

219 in my code is 'x' below..
----------------
List<ForumItem> items = getItemsInSite(siteId);

x    for (ForumItem item: items) {

         ret.add(item.id);
----------------

So added this line.. and it is exporting now..

if (items != null) {
     for (ForumItem item: items) {

Thanks
Omer
