jbpm工作流动态会签

前段时间，刚刚完成一个动态会签的，现在有点空，补上思路 

流程图：

 
 流程文件:

               <task-node name="签发" >
		<task name="签发" swimlane="qianfa">
         	<controller>
         		<variable name="PAGE_RESULT" mapped-name="qianfa"></variable>
         		<!-- 如果选择了会签人员(多个以","分隔),将保存到以下变量中 -->
            	<variable name="signmanid" mapped-name="signmanid"></variable>
            	<variable name="firstCollectiveSignmanid" mapped-name="firstCollectiveSignmanid"></variable>
            	<variable name="outsignmanid" mapped-name="outsignmanid"></variable>
            	<!-- 是否需要会签 -->
            	<variable name="needCollectiveSign" mapped-name="needCollectiveSign"></variable>
    	     </controller> 		
 		</task>
 		<transition to="需要会签"></transition>
	</task-node>
	
	<decision name="需要会签">
		<transition to="会签" name="是test">
			<condition expression="#{needCollectiveSign eq 'yes'}"></condition>
		</transition>
		<transition to="接收" name="否">
			<condition expression="#{needCollectiveSign eq 'no'}"></condition>
		</transition>
	</decision>
	<!-- 定义了有等待概念的，并不会自动创建的任务节点，同时添加进入事件 -->
	<task-node name="会签" signal="last-wait" create-tasks="false">   
                     <event type="node-enter">   
                        <action name="createInstance"    
                             class="cn.org.test.process.handler.action.CreateCollectSignInstanceHandler"/>   
                     </event>   
                     <task name="会签">   
        	         <controller>   
            		<variable name="PAGE_RESULT" mapped-name="huiqian"></variable>   
        	        </controller>   
    	     </task>   
    	     <transition to="join1"></transition>   
	</task-node>
	<!-- join自动结点，自动汇集多个token，等所有token都到达后，会自动触发transition，进行流向 -->
	<join name="join1">
		<transition to="接收"></transition>
	</join>
