Hi folks, me again :) My team stumbled on this issue recently, basically have a BKM which outputs a context which outputs a decision table containing one output column and validate this DMN through the KIE validator and we run into this validation error message: ``` The listed type reference could not be resolved - Message [id=0, level=ERROR, path=null, line=24, column=-1 text=DMN: Unknown output type for decision table on node 'MyBKM' (DMN id: _159C951D-5144-4891-B9BA-685D49D08F00, The listed type reference could not be resolved) ] ``` I did a bit of digging into the DMN XML and the Drools code and the error appears to be coming from `DMNEvaluatorCompiler::recurseUpToInferTypeRef` - it looks like this code doesn't handle the case where a `recursiveIdx.getParent(`) is of type `TFunctionDefinition`. Oddly, the code seems to handle the `instanceof BusinessKnowledgeModel` and a `BusinessKnowledgeModel` has a reference to the function definition. In addition, it looks like the editor might be taking some liberties in how it handles setting up the `output` and `decisiontable` XML elements when the decision table output is a single column (namely that the `name` and `typeRef` attributes are added to the `decisiontable` element and not to the `output` element). However, all this is just speculation on my part in terms of how it works/should work. We did notice however that a DMN using a BKM setup this way evaluates perfectly fine, and if, for example, you manually add the `typeRef` property to the `output` element of the decision table, the validation error goes away as well. Attaching a screenshot of the BKM setup and the DMN itself here:  [phil-context-stuff.zip](https://github.com/user-attachments/files/21024924/phil-context-stuff.zip) -- This is an automated message from the Apache Git Service.
