可流动：CMMN建模器错误转换CasePlanModel

Question

我已经通过Apache tomcat部署了Flowable 6.3.1。试图模拟以下模型Flowable BpmnJsonConverter（顺便说一句，我不知道它与CMMN建模有什么关系）抛出NullPointerException。 CMMN model

生成的xml如下。

我需要做些什么来解决它？

附：我以前有这个问题，当我试图部署它的应用程序时，它曾经抛出一个关于extensionElement标签的异常，以及它不应该有孩子的事实！但现在它没有任何例外地部署。

编辑1：我已经发现决策表引用为null所以当我改变它以指出决策表时，我得到了我之前在P.S中提到的相同的异常。部分。这是一个CmmnXMLException。堆栈跟踪摘要如下。

编辑2：我试图逐步构建案例，并发现CasePlanModel在添加表单时保存崩溃。建模器和引擎也存在集成决策任务引用的严重问题。

定义标记的最后一个参数是错误的：

targetNamespace="http://www.flowable.org/casedef"

应该：

targetNamespace="http://www.flowable.org/processdef"
