        ... 37 more

I have also checked the CleanupActionListener.java line that throw the nullPointer:
RequestContext.getCurrentInstance().release();

seems the currentistance is null...

by the way the tag is this:

Code: Select all

<h:dataTable value="#{attachmentBean.attachList}" var="attachment">
<p:commandLink ajax="false" title="Download">
     <p:graphicImage value="/img/icona_download.gif" height="20px" width="20px"/>
     <p:fileDownload value="#{attachment}" />
</p:commandLink>

I use jboss 5.0, jsf 1.2, facelet 1.14, primefeces: primefaces-1.0.2.jar

Any news?

Hi,

Try putting the commandLink inside a column also please read forum posting guidelines especially number 3.

http://primefaces.prime.com.tr/forum/vi ... f=3&t=1194

Thank you.

Sorry for the inconvenience, the code I have give isn't correct, in fact there is the <h:column> tag

Code: Select all

<h:dataTable value="#{attachmentBean.attachList}" 
                    var="attachment"
     <h:column>
        <f:facet name="header">
            <h:outputText value="#{msg.label_AttachFile}" />
        </f:facet>
        <p:commandLink ajax="false" title="Download">
              <p:graphicImage value="/img/icona_download.gif" height="20px" width="20px"/>
              <p:fileDownload value="#{attachment}" />
        </p:commandLink>
        <h:outputText value="  #{attachment.name}"/>
      </h:column>
</h:dataTable>

[trank]

Fixed, by using <h:commandLink> instead of <p:commandLink>

so, from:

Code: Select all

<p:commandLink ajax="false" title="Download">
              <p:graphicImage value="/img/icona_download.gif" height="20px" width="20px"/>
              <p:fileDownload value="#{attachment}" />
</p:commandLink>

to:

Code: Select all

<h:commandLink title="Download">
     <p:graphicImage value="/img/icona_download.gif" height="20px" width="20px"/>
     <p:fileDownload value="#{attachment}"/>
</h:commandLink>

Strange as showcase uses p:commandLink with no issues;

http://www.primefaces.org:8080/prime-sh ... wnload.jsf

[trank]

maybe is our configuration... we use jsf 1.2 (Myfaces) and primefaces 1.0.2, the showcase run on 2.1

[cagatay.civici]

I see but why do you have com.sun.lifecycle (Mojarra) classes in stack trace if you are using myfaces?

Hi,

I having the same problem , we have a primafeces' datatable that show several documents. If I use the <p:commandLink> it open the same file in all the cases. However, if I use the <h:commandLink> it works perfect :S

Code: Select all

<p:dataTable var="documento" id="tablaDoc-${solicitud.convenio.ssconvId}" value="#{solicitud.archivosConvenio}" styleClass="primefaces-skin">

        <p:column>
            <f:facet name="header">
                <h:outputText value="Nombre Archivo" />
            </f:facet>
            <h:outputText id="nomArchLab-${solicitud.convenio.ssconvId}-${documento.ssarchId}" value="#{documento.ssarchNombre}" />
        </p:column>

        <p:column>
            <f:facet name="header">
                <h:outputText value="Tipo" />
            </f:facet>
            <h:outputText id="tipoArchLab-${solicitud.convenio.ssconvId}-${documento.ssarchId}" value="#{documento.ssarchTipo}" />
        </p:column>

        <p:column>
            <f:facet name="header">
                <h:outputText value="Ver"/>
            </f:facet>
            <h:commandLink  id="desc-${solicitud.convenio.ssconvId}-${documento.ssarchId}" ajax="false" immediate="true">
                <p:graphicImage value="/resources/images/download.gif"  styleClass="img_sinborde"/>
                <p:fileDownload  id="downl-${solicitud.convenio.ssconvId}-${documento.ssarchId}" value="#{documento.contenido}" />
            </h:commandLink>
        </p:column>
        <p:column>
            <f:facet name="header">
                <h:outputText value="Eliminar" />
            </f:facet>
            <h:outputText id="eliminarButLab-${solicitud.convenio.ssconvId}-${documento.ssarchId}" value="" />
        </p:column>
    </p:dataTable>

We are using:

Glassfish 2.1.1
Mojarra 2.0.3

If you use p:commandLink, you need to set ajax="false" for filedownload to work.
