环境：jbpm4.4。
背景：用fork-join处理两个并行的分支(Task1,Task2)，当两个Task分别complete后按意图需要进入一个state节点，在此节点中完成业务相关的数据库操作，然后进入End。在state节点中写了一个EventListener(start)，但是两个Task分别有人Complete后，下一节点state的EventListener没有进入，不知道是何原因?
我做的是一个web项目，两个Task是不同的用户执行审批的，按照自己本身的想法，Task全部提交后应该进入下一个节点的state，但是EventListener没有执行，数据库JBPM4_Execution表显示节点已经进入state，我的问题是EventListener为何不执行?
下面是jpdl代码

流程到join后，直接进入order end(看数据库中JBPM_EXECUTION表可知)，但是order end之前应该先进入event-listener才对吧?
