Carregar os dados para edição em java JSF 2.3 + java 8

Programação
#1

Boa tarde pessoa, gostaria de um suporte para resolver uma situação pontual.

Atualmente tenho duas tabelas, tabela de Tonner e tabela de Location, ao tentar realizar a edição da Location, não consigo carregar o Tonner associado a Location, sempre e exibido a lista dos Tonners, porem não o tonner que estava associado a Location.

Segue abaixo os códigos.
