Closed FransBouma closed 8 years ago

A set of nested groups will lead to an exception:

Exception: System.InvalidOperationException

because the engine will create an index page for the group, but by doing that is changing the set of elements of the group (to add the index). This doesn't always succeed, as sometimes it can lead to the exception above.
