The method getRegionDTO() is undefined for the type Object
The method getRegionDTO() is undefined for the type Object
The method getRegionDTO() is undefined for the type Object
The method getFullName() is undefined for the type Object
The method getAdresseLabel() is undefined for the type Object

Answer 1

I just changed the version to groovy 2.0.1. I had the groovy 1.7.5 version which doesn't match the jasper 5.5.0.
This post helped me fix the issue.
