Hi I am trying to run a Java task with return var as a part of my JBPM flow. I could successfully pass input arguments to the class mentioned in Java task but while getting value back from the Java task it throws exception saying ... java.lang.NullPointerException at org.jbpm.pvm.internal.cmd.GetExecutionVariablesCmd.execute(GetExecutionVariablesCmd.java:60) at org.jbpm.pvm.internal.cmd.GetExecutionVariablesCmd.execute(GetExecutionVariablesCmd.java:36) org.jbpm.pvm.internal.svc.DefaultCommandService.execute(DefaultCommandService.java:42) at org.jbpm.pvm.internal.tx.StandardTransactionInterceptor.execute(StandardTransactionInterceptor.java:54) at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.execute(EnvironmentInterceptor.java:54) at org.jbpm.pvm.internal.svc.RetryInterceptor.execute(RetryInterceptor.java:55) at org.jbpm.pvm.internal.svc.ExecutionServiceImpl.getVariable(ExecutionServiceImpl.java:130) Please respond if someone has already faced and resolved this issue...
