[rules-users] problems with variables in drools-flow

I have a simple process with action and one human task. When I'm starting a process, I add a variable this way: Map<String,Object> data = new HashMap<String,Object>(); data.put("data3", "this is data3"); ProcessInstance pi = ksession.startProcess("com.sample.ruleflow",data); Another data I put in variable properties of the ruleflow, and called it data1. Third variable I added in action this way: ((org.drools.process.instance.context.variable.VariableScopeInstance) (context.getProcessInstance().getContextInstance(org.drools.process.core.context.variable.VariableScope.VARIABLE_SCOPE))).setVariable("data2", "this is data2"); But when I'm trying to map this variables in human task, only data1 is visible, the other end up with : Could not find variable scope for variable data2 when trying to execute Work Item Human Task Continuing without setting parameter. Could not find variable scope for variable data3 when trying to execute Work Item Human Task Continuing without setting parameter. Could you please help me? And also, how can I get this data in human task? I can get a task summary this way: BlockingTaskSummaryResponseHandler responseHandler = new BlockingTaskSummaryResponseHandler(); client1.getTasksAssignedAsPotentialOwner("martin", "en-UK", responseHandler); List<TaskSummary> list = responseHandler.getResults(); And then a task this way: BlockingGetTaskResponseHandler rh2 = new BlockingGetTaskResponseHandler(); client1.getTask(task.getId(), rh2); Task task2 = rh2.getTask(); But how can i get object data1? Thank you. Martin
