Good evening! Here is my problem:

I'm making a screen that has two calendars:

Theprogramwillreturnmealistcomprisingtheintervalbetweentwodates.Onedateisfromthefirstcalendar,andtheotherfromthesecondcalendar.

However,mycodebelowisnotworking.

<!DOCTYPEhtml><htmlxmlns="http://www.w3.org/1999/xhtml"

    <title>Sistema de Integração Moriah</title>
    <style type="text/css">
#painel {
    font-family: geneva, arial, helvetica, sans-serif;
    font-size: 100%;
    margin-top: 220px;
    margin-left: 300px;
    margin-right: 300px;
    text-align: center;
}

#form {
    padding-left: 60px;
}

</style>
</h:head>
<body>
    <ui:decorate template="menubardecorate.xhtml"></ui:decorate>
    <p:panel header="Selecione como deseja as Ordens de Serviço" id="painel">
        <h:form id="form">
            <h:panelGrid columns="5">
                <p:outputLabel value="Datas da OS:" />
                <p:outputLabel for="de" value="De:" />
                <p:calendar id="de" value="#{ListaOsBean.dataDe}" mindate="01/01/10" maxdate="" update="ate" />
                <p:outputLabel for="ate" value="Até:" />
                <p:calendar id="ate" value="{ListaOsBean.dataAte}" mindate="#{ListaOsBean.getDataDe()}" maxdate="" />
            </h:panelGrid>
        </h:form>
    </p:panel>
</body>
</html>

The "#{ListaOsBean.dataDe}" is not receiving the date passed by the user, and is not returning to the other <p:calendar/> in mindate="#{ListaOsBean.getDataDe()}" .

What I want is that once I click on the date of the first calendar, only become available in the second calendar, the numbers after the date that I selected in the first. This way:

MyBeanlookslikethis:

packagebr.com.moriahitg.bean;importbr.com.moriahitg.dao.SZA990DAO;importbr.com.moriahitg.modelo.SZA990;importjava.util.ArrayList;importjava.util.Date;importjava.util.List;importjavax.faces.bean.ManagedBean;importjavax.faces.bean.SessionScoped;importjavax.faces.context.FacesContext;importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpSession;@ManagedBean@SessionScopedpublicclassListaOsBean{List<SZA990>list=newArrayList<SZA990>();DatedataDe;StringdataDeS,dataAteS;@SuppressWarnings("unchecked")
    public String addOSNaListaPorCliente() {
        HttpServletRequest request = (HttpServletRequest)   FacesContext.getCurrentInstance().getExternalContext()
                .getRequest();
        HttpSession session = request.getSession(true);
        String a1_cod = (String) session.getAttribute("A1_COD");
        SZA990DAO szadao = new SZA990DAO();
        list = szadao.getOSPorCliente(a1_cod);
        return "/listaDeOSs.xhtml?faces-redirect=true";
    }

    public List<SZA990> getList() {
        return list;
    }

    public void setList(List<SZA990> list) {
        this.list = list;
    }

    public Date getDataDe() {
        return dataDe;
    }

    public void setDataDe(Date dataDe) {
        this.dataDe = dataDe;
    }

//  public Date getDataAte() {
//      return dataAte;
//  }

//  public void setDataAte(Date dataAte) {
//      this.dataAte = dataAte;
//  }

    public String getDataDeS() {
        return dataDeS;
    }

    public void setDataDeS(String dataDeS) {
        this.dataDeS = dataDeS;
    }

    public String getDataAteS() {
        return dataAteS;
    }

    public void setDataAteS(String dataAteS) {
        this.dataAteS = dataAteS;
    }

}

Should I use some listener, or ajax? Thank you in advance for the answer! I searched and did not find anything specific.

Use ajax, when the field loses focus you call the listener and invoke the set method to set the start date, then in the second field set the date to be the value set by the listener of the previous date. 

<p:calendar id="dataInicial" value="#{bean.dataInicial}">
  <p:ajax event="dateSelect" listener="#{bean.setDataInicial}" update="toDate" />
</p:calendar>

<p:calendar id="dataFinal" value="#{bean.dataFinal}"  mindate="#{bean.getDataInicial}"/>
