Classe Money e Percent - Erro ao Salvar
27/12/2012 21:35 0 Boa noite, amigos.

Estou com um problema que realmente não consigo resolver e preciso da ajuda de vocês.

Criei a classe "Money" e "Percent" que nada mais é que a cópia do "Double" (java), apenas alterando o toString() para um retorno mais amigável, além de separar melhor as atribuições.

Mapeei o GORM e ele tá usando o tipo certo no BD (double), porém, ao tentar salvar dá a seguinte exceção:

Adicionei o método toDouble() como tentativa, sem sucesso.
