JBPM 4.3 调用executionService.signalExecutionById之后并没有走到下一个state
我最近刚刚学习JBPM 4.3， 照着xyz20003的用户指南写了一个小的列子，如下：
processInstance = executionService.startProcessInstanceByKey("abcdefg",variables);
Execution exec = processInstance.findActiveExecutionIn("state1");
executionService.signalExecutionById(exec.getId(), "to end1");
Assert.assertTrue(processInstance.isEnded());
<process name="simplea" key ="abcdefg" xmlns="http://jbpm.org/4.3/jpdl">
<start name="start1" g="280,48,48,48">
<transition name="to state1" to="state1" g="-59,-17"/>
</start>
<end name="end1" g="272,261,48,48"/>
<state name="state1" g="269,156,92,52">
<transition name="to end1" to="end1" g="-47,-17"/>
</state>
</process>
最终junit判断processInstance.isEnded() 为false;
然后我重新修改代码打印调试信息
processInstance = executionService.startProcessInstanceByKey("abcdefg",variables);
Execution exec = processInstance.findActiveExecutionIn("state1");
executionService.signalExecutionById(exec.getId(), "to end1");
Set<String> activityNames = processInstance.findActiveActivityNames();
if (activityNames == null) {
System.out.println("current activityNames is null" );
}
else {
for (String name: activityNames) {
System.out.println("activity name is "+name);
}
}
Assert.assertTrue(processInstance.isEnded());
打印了activity name is state1
我想问的是：
executionService.signalExecutionById(exec.getId(), "to end1"); 这个语句不是会让流程走到下面一个state吗，为何触发之后状态还是active，怎么样走到end节点或者说下一个节点呢？
对processInstance重新赋值就可以了
很不幸，我执行的是预期的结果。。。。。 :o :o :o
我用的是JBPM4.2执行通过，4.3我也试着执行了一下，执行失败，结果跟你的一样。
感觉是4.3未发现的新BUG。。。
因为看了升级文档，没有任何提示从STATE到END要有什么变化，
[code="java"]
Release Notes for jBPM 4.3
Main improvements
Added BPMN 2.0 runtime engine!
Extended java activity with ejb method invocation. JBPM-2412
Added jms activity (including test facilities) JBPM-2300
Added integrated rules deployment and activities rules and rules-decision JBPM-2006
Added enhanced spring integration and created continuous integration for it JBPM-2529 & JBPM-2631
Automatic saving of updated deserialized variables JBPM-2684
Added count() capabilities to all queries in the api JBPM-2567
Fixes various bugs
DB changes
No DB upgrade necessary for upgrading from 4.2 to 4.3
API changes
DeploymentQuery.PROPERTY_NAME has been removed due to errors when sorting on name on Oracle (was already deprecated in a previous release).
DeploymentQuery.deploymentDbId(long dbid) has been changed to DeploymentQuery.deploymentId(String id) to be conistent with the query API.
The behaviour of taskService.getOutcomes(taskId) have been changed. See issue [JBPM-2492].
jPDL changes
No backward incompatible changes
Added jms, rules and rules-decision activities
Added attribute ejb-jndi-name to java activity
Added attribute propagation to all event-listeners
Configuration changes
Spring integration: Creating a processEngine bean is now done through the org.jbpm.pvm.internal.processengine.SpringHelper class (instead of the SpringConfiguration class). See the Spring chapter in the developers guide for more information.
Known Limitation
Reporting in the jBPM console does not work on Tomcat. See [JBPM-2627]

其实是你的代码有问题
因为虽然你在开始的时候新建了一个变量
[code="java"]processInstance = executionService.startProcessInstanceByKey("abcdefg",variables); [/code]
但是这个processInstance并不会随着你的流程的执行自动改变
processInstance = executionService.startProcessInstanceByKey("abcdefg",variables);
Execution exec = processInstance.findActiveExecutionIn("state1");
processInstance =executionService.signalExecutionById(exec.getId(), "to end1");
Assert.assertTrue(processInstance.isEnded());
惭愧，惭愧，正如楼上所说，
没仔细看代码，不好意思， :wink: :wink: :wink: :wink:
