Step 1: Create a variable in your process. (I use userComms, it's my POJO) https://community.jboss.org/servlet/JiveServlet/showImage/2-729764-18391/... https://community.jboss.org/servlet/JiveServlet/downloadImage/2-729764-18... Step 2: In the Human Task Parameter Mapping, map my variable to "Content". (I always have this problem doing this. See https://community.jboss.org/message/729763#729763#729763 https://community.jboss.org/message/729763#729763 ) https://community.jboss.org/servlet/JiveServlet/showImage/2-729764-18392/... https://community.jboss.org/servlet/JiveServlet/downloadImage/2-729764-18... Step 3: [Optional] In the On Entry Action of the Human Task, I set the value of my POJO. You can do it any way you like. Question: is the kcontext.setVariable() necessary? Step 4: Compile and run our process. Step 5: Accessing your variable from the task's "Content" And I got my POJO from the Content. Happy. :) -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/729764#729764] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
