节点不能有多个传入/传出边缘

Question

我想开始使用jbpm，我正在学习本教程。 http://www.mastertheboss.com/jbpm5/jbpm-5-tutorial-first-example?start=1 在第二页上，我必须添加一个分歧网关，融合网关，约束，将类型更改为XOR，并创建一个变量“money”。当我尝试运行该程序时，出现以下错误。

我试过调试，通过删除节点/边缘，直到我得到不同的错误。如果我删除整个分支，错误将是网关需要1 +边缘。如果我从其中一个分支中删除边缘，它会说该脚本具有多个传入/传出边缘。这似乎是，第二个脚本与不同的ID和名称，是与第一个混淆或有边缘，我看不到。

附加问题： 1.我如何知道它指的是哪个节点？ （我用日食，这通常会送你到一个代码行的链接不显示任何东西）

Answer 1

你能分享你的流程示意图形象？ 它正在引用通常是脚本节点的ActionNode。 我会推荐你​​使用web过程设计器，它在功能和验证方面要好得多。
