使用 MID 压缩输入的 DMN 决策模型
DMN decision model that zip inputs with MID
我有以下 DMN 模型可以压缩输入并计算折扣。我可以通过 Signavio 中的模拟器 运行 它。

我试过如下更改 zip
zip(["Item Name", "Item Price", "Item Quantity",order.itemName, order.price, order.quantity)
当我 运行 通过我的 java 代码时，我收到以下错误消息
19:40:43.251 [main] 错误 org.kie.dmn.feel.runtime.functions.DTInvokerFunction - 调用决策时出错 table 'determineDiscount': ClassCastException
java.lang.ClassCastException: class java.util.ArrayList 无法转换为 class java.math.BigDecimal（java.util.ArrayList 和 java.math.BigDecimal 在模块 java.base 中装载机 'bootstrap')
我的java代码会像这样
final KieServices ks = KieServices.Factory.get();
final KieFileSystem kfs = ks.newKieFileSystem();
KieModuleModel kmm = ks.newKieModuleModel();
kmm.setConfigurationProperty("org.kie.dmn.profiles.signavio", "org.kie.dmn.signavio.KieDMNSignavioProfile");

kfs.write(ks.getResources().newClassPathResource("MID Example (2).dmn", this.getClass()));
KieBuilder kieBuilder = ks.newKieBuilder(kfs).buildAll();

logger.info("buildAll() completed.");
results.getMessages(Message.Level.WARNING).forEach(e -> logger.warn("{}", e));

printDecisionResults(decResutls);
感谢任何指点。
感谢您提供所有必需的 assets/code 以完整重现该问题。
我相信有几个问题我将在下面描述，并提供一个完整的fixed/working示例底部。
问题：关于订单类型定义。
根据您完整的 DMN 模型定义，Order（输入数据节点值）必须是 "itemName", "price", "quantity" 属性的单例复合对象；每个 属性 都是一个集合。
所以输入应该是这样的：
order: {
itemName: [item1, item2, item3]
quantity: [100, 20, 300]
price: [1000, 200, 3000]
}
问题：尊重与订单类型定义一致的 zip 函数
根据您完整的 DMN 模型定义，zip 函数的正确定义应为：
zip(["Item Name", "Item Price", "Item Quantity"], order.itemName, order.price, order.quantity)
根据完整的 DMN 模型定义，我假设您想做的是将数据转换为以下结构
collateOrder: [
{
Item Name=item1,
Item Quantity=100,
Item Price=1000
},
{
Item Name=item2,
Item Quantity=20,
Item Price=200
},
{
Item Name=item3,
Item Quantity=300,
Item Price=3000
}
]
问题：MID聚合函数
我相信我在 Signavio 扩展实现中发现了一个错误；感谢您报告这将进一步调查。
但是，您可以使用更简单的标准 DMN 文字表达式来执行所需的业务逻辑，而不必依赖仅在 DMN 规范本身中定义的内容之外的任何扩展：
sum( for order in collateOrder return ( order.Item Price * order.Item Quantity ) )
这不需要任何 (Signavio) 扩展，并且它是有效的 DMN。
回顾一下。
Java 测试代码片段：
DMNContext context = runtime.newContext();
List<String> itemList = Arrays.asList("item1", "item2", "item3");
List<BigDecimal> priceList = Arrays.asList(new BigDecimal(1000), new BigDecimal(200), new BigDecimal(3000));
List<Integer> qtyList = Arrays.asList(100, 20, 300);
Map<String, Object> order = new HashMap<>();
order.put("itemName", itemList);
order.put("price", priceList);
order.put("quantity", qtyList);
context.set("order", order);
DMNResult evaluateAll = runtime.evaluateAll(model0, context);
固定 DMN 模型，不需要任何特殊扩展：

再次感谢您报告 MID 问题，我们将调查 Signavio 扩展中的问题。
我有以下 DMN 模型可以压缩输入并计算折扣。我可以通过 Signavio 中的模拟器 运行 它。

感谢任何指点。
感谢您提供所有必需的 assets/code 以完整重现该问题。 我相信有几个问题我将在下面描述，并提供一个完整的fixed/working示例底部。
问题：关于订单类型定义。
根据您完整的 DMN 模型定义，Order（输入数据节点值）必须是 "itemName", "price", "quantity" 属性的单例复合对象；每个 属性 都是一个集合。
所以输入应该是这样的：
order: {
itemName: [item1, item2, item3]
quantity: [100, 20, 300]
price: [1000, 200, 3000]
}
问题：尊重与订单类型定义一致的 zip 函数
根据您完整的 DMN 模型定义，zip 函数的正确定义应为：
zip(["Item Name", "Item Price", "Item Quantity"], order.itemName, order.price, order.quantity)
根据完整的 DMN 模型定义，我假设您想做的是将数据转换为以下结构
collateOrder: [
{
Item Name=item1,
Item Quantity=100,
Item Price=1000
},
{
Item Name=item2,
Item Quantity=20,
Item Price=200
},
{
Item Name=item3,
Item Quantity=300,
Item Price=3000
}
]
问题：MID聚合函数
我相信我在 Signavio 扩展实现中发现了一个错误；感谢您报告这将进一步调查。
但是，您可以使用更简单的标准 DMN 文字表达式来执行所需的业务逻辑，而不必依赖仅在 DMN 规范本身中定义的内容之外的任何扩展：
sum( for order in collateOrder return ( order.Item Price * order.Item Quantity ) )
这不需要任何 (Signavio) 扩展，并且它是有效的 DMN。
回顾一下。
Java 测试代码片段：
DMNContext context = runtime.newContext();
List<String> itemList = Arrays.asList("item1", "item2", "item3");
List<BigDecimal> priceList = Arrays.asList(new BigDecimal(1000), new BigDecimal(200), new BigDecimal(3000));
List<Integer> qtyList = Arrays.asList(100, 20, 300);
Map<String, Object> order = new HashMap<>();
order.put("itemName", itemList);
