I am trying to make a train help bot that tells trains between 2 particular stations as slots Source and Destination. Both slots take the same type of values ie. a station name, the same value can be source or Destination given its position. The form works fine when i give both slots in the same query like - Search trains from [Delhi](Source) to [mumbai](Destination). Search trains from [Mumbai](Source) to [delhi](Destination). however if I give 1 slot at a time it overwrites the previous values. Same code works in rasa 1.8.3 with sklearn pipeline language: "en" pipeline: - name: "SpacyNLP" - name: "SpacyTokenizer" - name: "SpacyFeaturizer" - name: "RegexFeaturizer" - name: "CRFEntityExtractor" - name: "EntitySynonymMapper" - name: "SklearnIntentClassifier" policies: - name: MemoizationPolicy - name: FormPolicy - name: TEDPolicy max_history: 5 epochs: 50 - name: MappingPolicy however when i use following diet classifier pipeline slots override language: en pipeline: - name: WhitespaceTokenizer - name: RegexFeaturizer - name: LexicalSyntacticFeaturizer - name: CountVectorsFeaturizer - name: CountVectorsFeaturizer analyzer: "char_wb" min_ngram: 1 max_ngram: 4 - name: DIETClassifier epochs: 50 - name: EntitySynonymMapper - name: ResponseSelector epochs: 100 output- [alt text] PNBE and NDLS are code for stations for api call. I am using rasa forms: class TrainSearch(FormAction): def name(self) -> Text: return 'train_form' @staticmethod def required_slots(tracker: Tracker) -> List[Text]: return ["Source","Destination"] def validate_Source( self, value: Text, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict[Text, Any]) -> Dict[Text, Any]: """Validate Source slot value""" if value: # print("Validating source for train search, source: ",value) sour = codes(value) value = sour # print("Validation source done, Source: ",value) return {"Source": value} else: dispatcher.utter_message(template="utter_wrong_Source") return {"Source": None} def validate_Destination( self, value: Text, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict[Text, Any]) -> Dict[Text, Any]: """Validate Destination slot value.""" if value: # print("Validating Destination for train search, Destination: ",value) dest =codes(value) value = dest # print("Validation destination done, Source: ",value) return {"Destination": value} else: dispatcher.utter_message(template="utte…

This is a bug ( extracting other slots in the form is broken · Issue #218 · RasaHQ/rasa-sdk · GitHub ) that we already fixed. It will be fixed with the next release.
