  • have you already have a look to `` as described in https://stackoverflow.com/questions/8875818/how-to-use-primefaces-pfileupload-listener-method-is-never-invoked-or-uploaded ? – Loic Mouchard Jul 31 '17 at 12:05
  • yes, I already bumped into that question in stackoverflow but nothing worked. The event is not even called. – Joe Jul 31 '17 at 12:11

You should remove or fill the update="" attribute from your fileUpload component. It "redirects" the files to a component after upload.
