[jira] [Created] (DAFFODIL-2615) group sharing causes obscure unparser runtime error

Mike Beckerle created DAFFODIL-2615:
---------------------------------------

             Summary: group sharing causes obscure unparser runtime error
                 Key: DAFFODIL-2615
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2615
             Project: Daffodil
          Issue Type: Bug
          Components: Back End, Middle &quot;End&quot;
    Affects Versions: 3.2.1
            Reporter: Mike Beckerle


 

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.
