HDC调试需求开发（15万预算）,能者速来！>>>
activiti版本5.22，定义了个usertask，分出两条flow，一条flow的condition是#{agree==1}，另一条是#{agree==2}，
代码如下：
Task task = taskService.createTaskQuery().processInstanceId("15001").singleResult();
taskService.setVariableLocal(task.getId(), "agree", 1);
taskService.complete(task.getId());
第三行报错，说找不到agree：localVariable不是这么用的吗？
org.activiti.engine.ActivitiException: Unknown property used in expression: #{agree==1}
Caused by: org.activiti.engine.impl.javax.el.PropertyNotFoundException: Cannot resolve identifier 'agree'
