Activity Synchronisation Error "One and Only One of the Fields Must Contain a Value"

What

While running the Activity synchronisation you get the below error based on the XML you are using.

Job log
Creating Activity with external id pres-21346
        INFO: Creating new Talk
        WARN: Wrong Activity degree of recognition classification 'State'. Please find available classifications in the Activity degree of recognition scheme. Classifications are case sensitive.
        ERROR: Got non controlled exception creating content
        ----------------- Validation error -----------------
        External organization is part of an either–or group, where one and only one of the fields must contain a value
        Organization is part of an either–or group, where one and only one of the fields must contain a value
        Event is part of an either–or group, where one and only one of the fields must contain a value
        Exception details
        Validation of content 'Talk(id=<null>, title=Racial attitudes on a Midwestern college campus)' failed:
        Validation errors:
        externalOrganisation: ValidationResult [code=validation.text.definedEitherOr, args=null, nestedProperty=null, value=null], propertyPath: externalOrganisation
        organisation: ValidationResult [code=validation.text.definedEitherOr, args=null, nestedProperty=null, value=null], propertyPath: organisation
        event: ValidationResult [code=validation.text.definedEitherOr, args=null, nestedProperty=null, value=null], propertyPath: event

Why

  • This error occurs because the content in the XML contains several relations to either an External organisation, Organisation and/or Event.
  • The type "Talk" is only allowed to have one relation to either an External organisation or Organisation or Event.
    • You solve this by changing the content in the XML to only have one relation to either an External organisation, Organisation or Event and all other fields are left empty.
