Hello, as additional comment, we have seen this bug with other customers' environments. Best, Mauro

The error occurs after the first close of the window (back button). After a code review and retesting I discovered the cause. Closing the window prevents reopening the webview error free because the containing window has to be created again. In my case the webview was recreated on reopening, but not the containing window. By moving createWindow() inside the eventlistener that opens the window, the error disappears.

   item_container_window = Ti.UI.createWindow();
   ...
   newsview.addEventListener('itemSelected', function(e) {
   	item_container_window = Ti.UI.createWindow();
   	itemview = new ItemView("news");
   	item_container_window.add(itemview);
   
   	itemview.showArticle(e.link); 
   	win.tab.open(item_container_window);
   });

   newsview.addEventListener('itemSelected', function(e) {
   	item_container_window = Ti.UI.createWindow();
   	itemview = new ItemView("news");
   	item_container_window.add(itemview);
   
   	itemview.showArticle(e.link); 
   	win.tab.open(item_container_window);
   });

I think this issues can be marked as resolved, programmer error after all.
