In Business Central's DMN Modeler, a decision table with "Unique" Hit policy and overlapping rules, when placed into a context, produces a Runtime Exception on validate. Error Message is: "[uuid] DMN: Validation of the DMN Model cannot be performed because of some runtime exception 'org.kie.dmn.model.v1_2.TContextEntry cannot be cast to org.kie.dmn.model.api.NamedElement'. (DMN Validation stopped on failed validation for some DMN Model)"

We expected to see 'DMN: Overlap detected: Overlap values: [...] for rules: [...]. UNIQUE hit policy decision tables can only have one matching rule' among the validation errors, and in fact this error is displayed when the decision table is not nested within a context.
