Hi,

I confirmed that our fix for DPD200575935 which was reported by another customer has fixed this problem. That fix was made on Dec 7th so it should be in 16.0 update 2 (which should be available shortly).

Sorry for the inconvenience. We don't know of any workaround.

Thanks, that's great.  In my case I was able to work around it by moving the nested struct definitions to the enclosing scope.
