Duplicate Field Selected error message

[Henzell]

I receive this error when I save a child record.
Apex trigger dlrs_Financial_Coaching_SessionTrigger caused an unexpected exception, contact your administrator: dlrs_Financial_Coaching_SessionTrigger: execution of AfterUpdate caused by: System.QueryException: duplicate field selected: Confidence_Obtain_Your_Credit_Report__c: (dlrs)

My use case is that I am rolling up from a Session record (child) to a Master record (parent). The field that I am aggregating, Confidence_Obtain_Your_Credit_Report__c, is used in 2 rollup summaries. One rolls up using the First aggregate function, with aggregate result field being field A on the parent. The other rolls up the same field, but uses the Last aggregate function, with aggregate result field being field B on the parent.

The error occurs when I have both rollups in Realtime calculation mode. If one rollup is in Realtime and the other is in Scheduled mode, then the error message does not appear.

Ok this sounds like a bug, can you include a screenshot of both your rollups please?

[Henzell]

Screenshots attached. I'm hoping I can get around the issue by having one rollup work in Realtime, and the other Scheduled.

Ok this is a bug, i'll mark it as such. Sorry about this.

I have now fixed this in the GitHub master branch, and will be releasing in a new managed package for install shortly.
