Duplicate local variables are created in the View beans of the generated Faces scaffold

Local variables generated in the delete() method containing the deletion logic are named after the types of the properties. Multiple properties of the same type or parameterized type can exist in the JPA entity.

This was noticed in the JPA entities generated from the Sakila-H2 model.

A better naming convention needs to be used to prevent naming conflicts and eventually syntax errors in the generated scaffold.
