fiz o debug
tenho este stack:

Fala mano, boa tarde, tudo bem contigo?
Mano consegui depois de muita luta fazer “praticamente tudo” funfar legal aqui
Na imagem abaixo o campo que estava em VARCHAR(255) agora está DOUBLE
E nesta próxima imagem o valor está sendo gravado corretamente:
mas agora está rolando um erro em tempo de execução, não impede o funcionamento da aplicação, mas é um erro e um erro deve ser corrigido…hehehe
Toda vez que clico em Add Produto:
o produto é adicionado corretamente na grid, mas da este erro em execução(lembrando que não impede o funcionamento da aplicação):

Fui ver a linha 426 da classe VendaView:
mas confesso que não sei o pq do erro…alguma ideia?
Bem capaz que o event.getValue() esteja retornando NULL. Pode ser que esse txtProdutos não estivesse com um valor válido qdo o evento valueChangeListener foi acionado.
