如果我添加filteredValue属性，primefaces数据表中的commandLink将不起作用

Question

I have a primefaces datatable with a <p:commandLink> in each row. The user clicks it to see a different page with details about the record he selected. It was working fine until I add a filteredValue in my datatable. I need this attribute (filteredValue) in order to correctly filter and sort my datatable, as shown in this question .

But after adding this attribute, my commandLink stops working. How can I make it work with the attribute?

Here's my datatable:

<p:dataTable var="prot" value="#{myBean.listaProtocolos}" rows="15" filteredValue="#{myBean.listaProtocolosFiltrados}" sortBy="#{prot.dataEntradaArea}" sortFunction="#{myBean.sortXMLDatas}" sortOrder="descending" paginator="true" style="font-size: 0.9em;" paginatorPosition="bottom">
  <p:column filterBy="${prot.nrProtocolo}" filterMatchMode="contains" width="8%" style="text-align:center">
    <f:facet name="header">ID</f:facet>
    <p:commandLink action="#{myBean.verDetalhesProtocolo}" process="@this messages" update="@this messages">
      <h:outputText value="#{prot.nrProtocolo}" style="text-decoration: underline;"/>
      <f:setPropertyActionListener target="#{myBean.nrProtocolo}" value="#{prot.nrProtocolo}" />
    </p:commandLink>
  </p:column>
(etc)

and the relevant pieces of myBean:

public void verDetalhesProtocolo() {
    for(ProtocoloMY pro : this.listaProtocolos){
        if(pro.getNrProtocolo().trim().equalsIgnoreCase(this.nrProtocolo.trim())) {
            this.protocolo = new ProtocoloMY(pro);
            break;
        }
    }
    FacesContext facesContext = FacesContext.getCurrentInstance();
    facesContext.getExternalContext().redirect("detalhes_protocolo_processo.xhtml");
    //(This method isn't even called when I add the attribute filteredValue to my datatable)

public String getNrProtocolo() {
    return nrProtocolo;
}

public void setNrProtocolo(String nrProtocolo) {
    this.nrProtocolo = nrProtocolo;
}
    public List<ProtocoloMY> getListaProtocolos() {
    return listaProtocolos;
}

public List<ProtocoloMY> getListaProtocolosFiltrados() {
    return listaProtocolosFiltrados;
}

public void setListaProtocolosFiltrados(List<ProtocoloMY> listaProtocolosFiltrados) {
    this.listaProtocolosFiltrados = listaProtocolosFiltrados;
}

public void setListaProtocolos(List<ProtocoloMY> listaProtocolos) {
    this.listaProtocolos = listaProtocolos;
}

And I almost forgot to say: There's some network traffic happening when I click the link, but nothing is shown in my backend console and the method in my bean isn't called.

I'm running primefaces v6.0.

为了使PrimeFaces能够通过其唯一ID跟踪哪一行，您需要使用行POJO中使其唯一的值添加属性rowKey =“＃{row.id}”到p：datatable中。
