}Caso eu crie um main e teste o metodo da TesteJSF a lista retorna com todos os objetos!
Mas quando eu tento jogar para uma pagina dá o erro descrito!
a pagina contem
<f:view>
<h:dataTable value="#{testeJSF.carros}" var="carroa">
<h:outputText value="#{carros.codCarro}"></h:outputText>
<h:outputText value="#{carros.cor}"></h:outputText>
</h:dataTable>
</f:view>Desde já agradeço a ajuda!!!
