Problems with ireport

0

I'm trying to generate a simple report with three filters: datainicial, datefinal, and reservoir. The problem is that clicking the button to generate the report nothing happens, and I do not get any messages on the console. I have already put prints and I saw that the method is being called. I also noticed that when I remove the filters from the method my report in pdf is generated smoothly. Here are the codes. xhtml:                                            

                <h:form id="formGrid">
                Data Inicial: <p:calendar id="popup" value="#{relatorioHistoricoMB.dataInicial}" />
                Data Final: <p:calendar id="popup2" value="#{relatorioHistoricoMB.dataFinal}" />
                <p:selectOneMenu value="#{relatorioHistoricoMB.reservatorio.idReservatorio}"
