Improper handling of duplicate columns in the ESRI shapefile reader
-------------------------------------------------------------------
Key: GEOT-3554
URL: http://jira.codehaus.org/browse/GEOT-3554
Project: GeoTools
Issue Type: Bug
Components: data shapefile
Affects Versions: 2.7.0
Reporter: S Anwar
Assignee: Andrea Aime
Attachments: gt-2.7.x-shapefile.patch.txt
The ShapefileAttributeReader does not properly resolve field names to their
indices for duplicate fields. Duplicate fields get the value of geometry due to
the fall-through case in the ShapefileAttributeReader.
The ShapefileDataStore does assigns the duplicate field a new name, but
knowledge of the original field name or the duplicate instance number are not
preserved. As a result when the ShapefileAttributeReader tries to resolve field
names to their indices, it cannot find the field.
The included patch is against branches/2.7.x.
