The CounterfactualExplainer has several limitations.

• SEARCH DOMAINS:
  • Structures and Collections: disabled
  • Strings: Disabled
  • NUMERICALS: Must have distinct min and max values (i.e. min != max)
• GOALS:
  • Structures and Collections disabled
  • Strings: ENABLED

These need to be handled/reported in the UI.

Furthermore, if a (DMN) model only contains unsupported inputs/outputs (i.e. structures or collections) then show a PatternFly BullsEye component explaining the limitations to the User.

PMML models are not traced through Trusty and hence will not be candidates for Counterfactual processing.
