Views data export user role field value missing from exported csv file I'm using views_data_export to export data from the views displays. I added a Data Export option to the user account list views. When I use the batch in export settings, user role field is missing in the exported CSV file. While not using batch, role field is there. 



Thanks
I found this is a bug in the module itself, and the following patch will solve the issue.
