Hi, all:
    i can use the method : startProcessInstanceByKey(String processDefinitionKey, Map<String, Object> variables) to create a processInstence, when i query someone's  task list through taskService.createTaskQuery().processVariableValueEquals("key", "value").taskAssignee("assignee"), i get a tasklist, how can i get the process's variables ( to show in sb's  task pool) except invoke a method (i think repeat invoking another mehtod is not reasonable)
