activiti 6: Retrieve uploaded file form

Question asked by med.amine on Dec 7, 2018


am uploading a file in a usertask form. I want to know how to retrieve that file in a servicetask; specifically in the execute method of the class that implements JavaDelegate.

When I try to access the variable through execution.getVariables("field_file_id"); I get a nullvalue.

I am using activiti 6

I appreciate any help you could provide me. Thanks in advance.
