View.Duplicate WithDetailing fails if Attached Detail Groups are in the view

[thomas]

I appear to have stumbled upon a possible bug in the Revit 2017 API (not tested newer versions). 

Calling View.Duplicate(opt) where opt = ViewDuplicateOption.WithDetailing fails if the view has attached detail groups. As soon as I delete the attached Detail groups, everything works as expected. 

Is this a known bug? If so, are there any workarounds?

Hello!

I am having a very similar problem with Revit 2018. It looks like Duplicate with Detailing has a confilct with duplicating attached detail groups. 

Have you come to an answer regarding this issue?

Thank you in advance!
