Pessoal, bom dia.
Alguem pode me ajudar com o erro abaixo?
Estou usando JPA + HIBERNATE + VRAPTOR
Classes:
a) Feature.java
b) A Feature possui FeatureLicense.java tendo um relacionamento OneToOne
A sequência do processo:
a) É aberta uma página para digitação das chaves de uma licença ( FeatureLicense.java)
b) Assim, o controller recebe a instância de Feature/FeatureLicense pelo mapeamento das classes e seus atributos. Exemplo: feature.license.keyACode/ feature.license.keyBCode
c) Quando o controller recebe as instâncias descritas acima, os dados da feature neste momento estão vazias, por isso faço uma pesquisa da feature como detached(featureGov) e em seguida faço um set em feature com os dados de featureGov. Neste parse atualizo apenas o ID, o código da feature e em licença, atualizo a feature por causa do relacionamento.
Depois deste processo, serializo o objeto para atualizar alguns campos indicando se a chave é válida e data de expiração. Isto antes de salvar os dados na base.
a) result.use(ExtJSJson.class).from(feature).success(true).serialize();
Nesta serialização está gerando o erro abaixo:
