Hi All,
 I am facing one problem when completing a Human task. The problem arises when I use Spring drools integration. I am getting the ksession from spring bean. using that I am starting the process Instance. The process contains one human task. I am using SyncWSHumanTaskHandler and LocalTaskService. On call of task completion it throws exception as below
