In my workflow i have Dialog participation step in which i mapped the dialog contains widget having value ./val. Next is process step. I want to fetch the value of dialog's val inside process step. After start WF, When i checked process step logs. i found from map /etc/workflow/instances/2014-09-21/model_20811320033046/history/1411239008186, no node under it shows not any value set with val. Please tell how i can fetch this value in my process step.
