I have this same problem I write the post on tuesday if i submit the form without any files and i check $this->request->hasFiles() i have true but my $_FILES array is [name] =>
[type] => [tmp_name] => [error] => 4 [size] => 0 UPLOAD_ERR_NO_FILE Value: 4; No file was uploaded. I think there is the problem
