Erro ao Salvar objetos com HIBERNATE

Boa tarde pessoal, estou com um problema na hora de salvar dois objetos de forma sequencial em um banco informix. Eu tenho que salvar em duas tabelas sem relacionamento os dados de que estão preenchidos em dois objetos (objA e objB). Quando eu chamo os dois metodos session.save para salvar esses objetos, os dados não são inseridos no banco e ainda me aparece uma mensagem abaixo.
Quando eu colocovalidator.onErrorUse(http()).setStatusCode(200); os dados são salvos no banco. Alguem ai sabe me dizer como eu resolvo este problema, pois eu NÃO UTILIZO VALIDAÇÃO (VALIDATOR) NESTE CONTROLE. ABRAÇÃO E BOM FIM DE SEMANA

na linha 6:

If you didn't add any validation error, it is possible that a conversion error had happened.

ou seja, vc está passando algum parâmetro no formato errado, por exemplo passando letras num campo que espera número…

Obrigado Lucas! Consegui resolver o problema. havia um erro com a data que eu estava passando para a aplicação. Foi necessário baixar o source do vraptor para poder debugar e localizar o erro.

aconteceu um erro de conversão, assim como a mensagem de erro disse que poderia acontecer.

Mas tem razão, essa mensagem poderia ser mais clara
