Mike Beckerle commented on DAFFODIL-2615:
-----------------------------------------
Added to 3.4.0 release target because many DFDL schema projects are having to
work around this by duplicating (and therefore not sharing) what would
otherwise be shared groups.
> group sharing causes obscure unparser runtime error

> While working on a large DFDL schema, ran into a problem where a group is
> being shared in 2 places.
> I get an obsure message at unparse time like this:
> "Unparser needed event for {}nackHeader but got (invalid) {}nackHeader"
> This element nackHeader is the element that appears immediately after *one*
> of the shared group references. The other one works fine.
> Making a copy of the shared group so that it is no longer shared eliminates
> the problem and is the workaround.
> I will endeavor to create a simplified scenario to reproduce.
