Camunda：如何让 DMN 发出两个 variable/values 到 BPM 工作流程的上下文？
Camunda: How to get DMN to emit two variable/values to context of BPM workflow?
我想要将 DMN 行的两个输出值发送到 BPMN 上下文，例如 DMN.output.var1=val1, DMN.output.var2=val2.
输入：（SPACE=法律，事物=破坏）
输出：(ROUT_TO_DEPT=BY_LAW,OUT_CATEGORY=检验)
这两个变量必须在上下文中，并且可用于 BPMN 的下一步。
但是我遇到了一个错误，如何让它发生？

我试图将其作为 resultList 变量，但我想要的是两个输出变量 - 一个元组。
编辑 1： 如果我选择 "singleResult" 选项，我可以将其作为单个变量中的地图获取，但是我想要两个变量BPMN 流程中的下一步。
到resultList的映射用于映射具有多个输出列的行列表。
切换到 singleResult 是正确的方向。您正在使用命中策略"First"（仅一个规则/行），因此地图决策结果属性只能是singleEntry（一个输出列）或singleResult（多个输出列）。
将决策结果映射到singleResult后，可以使用[=51=中的Input/Output选项卡 ] 面板将结果条目映射到过程变量：
在输出映射的文本字段中，您可以使用统一的表达语言，例如${deptRoureDetail.get('ROUT_TO_DEPT')}
访问Map类型的结果变量（在你的例子中是deptRoutDetail）并通过它们的键访问所需的字段（ROUT_TO_DEPT等）。
