Esta pregunta ya tiene una respuesta aquí:
Mostrar resultados de Hibernate / JPA en causas de tabla de datos JSF: java.lang.NumberFormatException: Para la cadena de entrada: “[nombre de propiedad]” 2 respuestasTengo el siguiente método en un bean de respaldo JSF:
public List<Rent> getTopMemebers(){
return rentDAO.findByMonthAndYear(MonthReport, YearReport);
}
Estoy mostrando esto en una tabla de datos:
<p:dataTable value="#{rentController.topMemebers}" var="item">
<p:column>
<h:outputText value="#{item.rentid}"/>
</p:column>
...
