Decision History should not thrown an exception if the input/outputs where fetch but are empty

XMLWordPrintable

      Scenario

      • A decision table is evaluated but it has not input or output values, (for example see attached DMN file)

      Problem

      • If you query for the historic decision instances including input and outputs like:
      List<HistoricDecisionInstance> decisions = BpmPlatform.getDefaultProcessEngine().getHistoryService().createHistoricDecisionInstanceQuery()
  .decisionDefinitionKey(decisionDefinitionKey)
  .includeOutputs()          
  .list();

      and then try to access the outputs or inputs there will be an exception

      for (HistoricDecisionInstance decision : decisions) {
  List<HistoricDecisionOutputInstance> outputs = decision.getOutputs();
  ...
}

      Caused by: org.camunda.bpm.engine.ProcessEngineException: ENGINE-03061 The output instances for the historic decision instance are not fetched. You must call 'includeOutputs()' on the query to enable fetching.

      AT

      • if the input/outputs are fetch during the query but are empty an empty list will be returned by getInputs and getOutputs instead of an exception
