Hi, I'm new in jBPM and I'm trying to do process where user can fill the form put there data (name, id..., mail) and this is data object (DesignTask) mail is in clientMail. As almost last task I have service task, which is sending mail. I want to setup as input data this DesignTask.clientMail https://ctrlv.cz/shots/2018/06/04/biRV.png but this is not working and I don't know how to set up there this var. If I to set up there constant (email@example.com) the sending mail is working on this mail adress.
Can someone please help and tell me which way I can do it?
