in the CMS, i keep getting the message:
Notice: Trying to get property of non-object in C:\xampp\htdocs\silverstripe_behf2\sapphire\forms\TreeDropdownField.php on line 127
the message suddenly appeared after building some page types and corresponding pages, when clicking on some page of type 'Virtual Page' in the Sitetree (Site Content).
i did a fresh install, copied my project, rebuilt the database, and again the message appears; this time when clicking on a deleted page (
see attached screenshot upload didn't work?).
for now, i solved the problem setting 'error_reporting(E_ALL ^ E_NOTICE)' in _config.php, but this is pretty ugly.
i'd appreciate any help on this topic.
thanks in advance
