Accordion panel appears open, but doesn't show content
问题 I want to show the first tab, and by default (I mean, without activeIndex ) it shows me that tab, but it doesn't show the content. <p:accordionPanel id="acordeon" value="#{editarReporteExcelBean.reporteOperacionDtoList}" var="reporteOperacion" activeIndex="0" > <p:tab id="areaTab" > <f:facet name="title">Area #{reporteOperacion.area.nombre}</f:facet> <anglosgi:reporteOperacion id="reporteOperacion1" reporteOperacionDto="#{reporteOperacion}" formId="reporteForm" contenedorId="reporteForm
