Hey all,

I'm new to silverstripe and trying to combine two dataobjects into an ArrayList and then sort it by Date/Created but It doesn't do the sort. I've included the code below.

$displayContent = ArrayList::create();
      
      $projectPages = ProjectPage::get()->sort('Created', 'DESC');
      $blogPages = BlogEntry::get()->sort('Created');

      foreach ($projectPages as $projectPage) {
         $displayContent->merge($projectPage);
      }
      foreach ($blogPages as $blogPage) {
         $displayContent->merge($blogPage);
      }

      $displayContent->sort('Created');

      return $displayContent;

Thanks for any help

David

Lists are mostly immutable (i.e operations on lists give you back new lists) so when you do your sort you need to get your list

$sorted = $list->sort('Created');
