selectEvent is null

Question

Previously, I used java ee 7 and glassfish 4 and my code was working correctly. After switching to Jakarta ee 8 and payara the selectEvent used is returning null. Follow the code below.

html

<sys:inputConverter convUpdate=":form1:mensagem" entidade="Religiao" 
                                                        objeto="#{alunoJsfBean.crudObj.religiao}" 
                                                        prepBuscaMetodo="#{bscBean.abrirPesquisaReligiao()}" />

        }
        Object objeto = getValueExpression("objeto").getValue(context);
        if (objeto == null) {
            return "";
        }
        if (objeto instanceof List) {
            List<Object> objects = (List<Object>) objeto;
            if (objects.isEmpty()) {
                return "";
            } else if (objects.size() == 1) {
                return objects.get(0).toString();
            } else {
                return objects.size() + " Itens selecionados";
            }
        } else {
            return objeto.toString();
        }
    }

    public void selectObj(org.primefaces.event.SelectEvent event) {
        if (event.getObject() == null) {
            return;
        }
        ELContext context = FacesContext.getCurrentInstance().getELContext();
        ValueExpression ve = getValueExpression("objeto");
        if (event.getObject() instanceof List) {
            List<Object> lst = (List<Object>) event.getObject();
            List<Object> retorno = new ArrayList<>();
            for (Object value : lst) {
                retorno.add(value);
            }
            ve.setValue(context, retorno);
        } else {
            ve.setValue(context, event.getObject());
        }
        JsfUtil.getJsfBean(GerBean.class).getObjetosSelecionados().clear();
    }
}

In the selectEvent method the event is null. If I pass the selectObj () method directly in the ajax listener, it works.

 <p:commandButton id="btnPesquisar" value="#{cc.attrs.nameBtn}" icon="#{icon.pesquisar}" process="@this #{cc.attrs.prepBuscaProcess}" update="@this #{cc.attrs.prepBuscaUpdate}" actionListener="#{cc.attrs.prepBuscaMetodo}" disabled="#{cc.attrs.disabled}" title="Abrir Pesquisa" tabindex="-1" styleClass="styleClass">
                <p:ajax event="dialogReturn" listener="#{cc.selectObj}" update="@parent #{cc.attrs.dialogReturnUpdate}"
                        oncomplete="PrimeFaces.focus('#{cc.clientId}:codigo');#{cc.attrs.dialogReturnOncomplete}" />
                <p:resetInput target="#{cc.clientId}:codigo" rendered="#{cc.attrs.resetInput}" />
            </p:commandButton>

Why is this happening?
