Olá pessoal!
Estou tentando inserir dados em uma tabela de relacionamento muitos para muitos, a aplicação é um sistema escolar, e estou inserindo uma turma e seus respectivos alunos no banco de dados, para isso estou usando o picklist do primefaces para puxar todos os alunos cadastrados no banco de dados, e selecionar só os que eu quero que façam parte da turma. Eu consigo inserir todas as informações normalmente, no console do eclipse eu consigo identificar o insert que ele dá na table Turma, só que na hora de dar o insert na tabela de relacionamento Turma_Alunos, apresenta o seguintes Erro: Caused by: java.lang.IllegalArgumentException: Can not set int field br.com.digitaltech.model.Aluno.id to java.lang.String**Erro completo** > GRAVE: JSF1073:
