Creating Outages from the Outage related list on the Change Request form causes duplicate outage records to be createdIssue The Outage related list on the Change Request form by default only lets you Edit (add/remove existing records) items in the list. When the New UI action is enabled and used to create outages, it results in duplicate outages being associated to that Change.CauseThe problem here is adding the New button to the related list causes the behavior. The New button does not appear on the related list by default and must be added via unchecking the Omit New checkbox on the List Control record for the Outage related list. The New button on a related list creates a new record on the related table and a record on the m2m table which links the new record on the related table to the current record. The create outage form consists of the outage fields and a task field. It will create an outage record, and an m2m record to link that outage field to the task referenced in the task field. This is not designed to be triggered by a source that contains subsequent linking actions. The outage form creates the link between the task and the outage specified, then the related list New action completes its processing by adding a link between the outage record that was just created and the task that contained the related list with the New button. Essentially: The outage form by design creates a record and links it to the task specified.The related list New button creates a record and links it to the parent record.ResolutionInstead of enabling the New UI Action on the Outages related list, use the Create Outage UI Action from the Task-Outage Relationship plugin, see Task Outage.
