Found a way around this... believe it or not, this is still an issue in Revit 2014.
We had some huge detail groups that didn't want to copy from one Drafting View to another Drafting View. Apparently there is no way around this BUT you can create the huge group beforehand and Duplicate with Detailing and create a duplicate of the entire view. Now you can go on and mirror this group and apply transformations, changes will propagate correctly between the two.
You will have to use this view from now on and copy all other elements to it.
This information was given under Help topic regarding copying ..
View-specific elements should be copied using the method that copies from one view to another. That method can be used for both view-specific and model elements however, drafting views cannot be used as a destination for model elements. The pasted elements are repositioned to ensure proper placement in the destination view. For example, the elevation is changed when copying from one level to another. An additional transformation within the destination view can be performed by providing the optional Transform argument. This additional transformation must be within the plane of the destination view.
Hence the error...
The text from the Help section is not relevant to the issue here and this remains a bug in Revit 2014.
Pasting model elements into a drafting view is a different (and obvious) issue. Moving 2-D ELEMENTS from a drafting view TO a section view should be possible but is not always. The problem is sporadic - some elements will copy from some views while others will not copy to different views.
We had the same error for drafting view, when trying to "Insert Views from File"
This happened because users were including dimension strings in detail groups
Tested each detail by copy paste into an empty drafting view to find the corrupted view
Some views had no dims anymore, but the bug hangs around
Did not have to duplicate view with detail, just grouped all of the elements and mirrored twice, then ungrouped.
