[I] DMN 1.5/1.6: typeRef on throws UnsupportedOperationException in 10.2 (regression from 10.1) [incubator-kie]
tpolaske opened a new issue, #7182:
URL: https://github.com/apache/incubator-kie/issues/7182
### Describe the bug
In 10.2.0, `org.kie.dmn.model.v1_5.TUnaryTests` (and v1_6) changed from extending `v1_5.TExpression` to `impl.AbstractTUnaryTests`. `AbstractTUnaryTests.setTypeRef()` throws `UnsupportedOperationException("Not on DMN v1.2")`.
The DMN 1.5 and 1.6 schemas (including the XSDs shipped in `kie-dmn-validation-10.2.0`) define `tUnaryTests extends tExpression`, which carries an optional `typeRef`. So `<inputValues typeRef="string">` is valid, but it can no longer be unmarshalled.
The KIE DMN editor (kie-tools 10.1) writes this attribute: changing an input clause's **Type** in the side panel creates `<inputValues typeRef="…"><text></text></inputValues>`. Models authored in the 10.1 editor stop loading on the 10.2 engine.
**Steps to reproduce**
1. Take any DMN 1.5 model with a decision table and add `typeRef="string"` to an input clause's `<inputValues>`.
2. Build it with `DMNRuntimeBuilder.fromDefaults().buildConfiguration().fromResources(...)` on 10.2.0.
**Expected:** The model builds (as on 10.1.0).
**Actual:** The marshaller swallows the `UnsupportedOperationException`, `Definitions` comes back null, and the build fails later with
`NullPointerException: "definitions" is null`.
**Suggested fix:** Have v1_5/v1_6 `TUnaryTests` support `typeRef` again (override get/setTypeRef, or restore the `TExpression` parent), as the spec allows.

Thanks @tpolaske to report that!
And thanks to @yesamer to fix it so fast!

Hi @yesamer, thanks for taking a look!
It affects both **DMN 1.5 and DMN 1.6**. I've attached a minimal reproducer (`inputValuesTypeRef_dmn15.dmn`). The only notable part is this input
clause:
<dmn:inputValues id="_B10" typeRef="string">
<dmn:text></dmn:text>
</dmn:inputValues>
This exact shape is written by the KIE DMN editor (10.1): selecting an input column's **Type** in the side panel adds `typeRef` to `<inputValues>`. It's valid per the 1.5/1.6 XSD (`tUnaryTests extends tExpression`, which has an optional `typeRef`).
**Steps to reproduce**
1. Build the attached model with kie-dmn-core 10.2.0:
```java
DMNRuntime runtime = DMNRuntimeBuilder.fromDefaults()
.buildConfiguration()
.fromResources(List.of(ResourceFactory.newClassPathResource("inputValuesTypeRef_dmn15.dmn")))
.getOrElseThrow(RuntimeException::new);
2. Evaluate decision Approval with input RiskCategory = "High".
Expected (behavior on 10.1.0): the model builds and Approval = "Review".
Actual (10.2.0): unmarshalling fails with UnsupportedOperationException: Not on DMN v1.2 from AbstractTUnaryTests.setTypeRef. The marshaller swallows it, Definitions comes back null, and the build then fails with NullPointerException: Cannot invoke "Definitions.getNamespace()" because "definitions" is null.
If you remove typeRef="string" from <inputValues>, the same model builds and evaluates correctly on 10.2.0.
Likely cause: in 10.2.0, v1_5.TUnaryTests / v1_6.TUnaryTests extend impl.AbstractTUnaryTests (previously TExpression), whose setTypeRef throws.

Hi @tpolaske,
I'm having some difficulty understanding the nature of the issue.
Is your DMN file based on DMN 1.5 or DMN 1.6?
Could you please provide clear steps to reproduce the problem, including any relevant inputs, expected results, and actual results?
Thanks!
