Olá Pessoal,
Estou tentando após uma pesquisa, carregar um DataTable abaixo, trazendo os valores da pesquisa.
A página é exibida normalmente, mas quando clico em “Buscar”, aparece um erro.
Estou usando JSF + PrimeFaces + Hibernate com JPA.
Peço desculpas antecipadamente caso esteja violando alguma das regras do fórum. Esse trabalho é para amanhã, estou um pouco ansioso. hehehe
Segue abaixo código do Bean, da página XHTML e o stacktrace.
