Error setting null for parameter #1 with JdbcType OTHER

[gi00vani_kun]

I'm trying to create a new task on an complete event

<activiti:taskListener event="complete" class="ec.eu.activiti.listener.UserListener"></activiti:taskListener>

Java Code below :

ProcessEngine processEngine = ProcessEngines            .getDefaultProcessEngine();      TaskService taskService = processEngine.getTaskService();         SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");       Task task = taskService.newTask();       task.setDescription("description 12131");       task.setName("taskname 2121");       task.setPriority(50);       task.setAssignee("dataexpert2");       task.setOwner("dataexpert2");       Date dueDate;      try {      dueDate = sdf.parse("01/05/2015 04:05:06");      task.setDueDate(dueDate);                  } catch (ParseException e1) {         // TODO Auto-generated catch block         e1.printStackTrace();      }      taskService.saveTask(task);‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I believe this is an Activiti Engine question can it be moved there ? I don't seem to have the rights or means to do it.
