fileupload reRender

[jmchiaradia]

Hello,

I have a fileupload field and I want to show it only if the file is not uploaded yet.
For the upload I have used rich:fileUpload with an uploadListener method for attach the upload data to my attachedCopy property.

The upload is working ok, I can upload any file and when I save the entity, the upload data is saved too, but I have the problem that the reRendering is not working well (or at least as I think it should work).

Here is the xhtml component:

<s:decorate id="attachedCopyField" template="/layout/edit.xhtml">
     <ui:define name="label">Adjunto</ui:define>
     <rich:fileUpload id="notaAdjunta"
          rendered="#{outNoteHome.instance.attachedCopy == null}"
          fileUploadListener="#{outNoteHome.processUpload}"
          immediateUpload="true" ajaxSingle="true"
          reRender="attachedCopyField">
     </rich:fileUpload>
     <s:button value="Download"
          rendered="#{outNoteHome.instance.attachedCopy != null}"
          action="#{fileDownloadBean.downloadFile(outNoteHome.instance.attachedCopy)}" />
</s:decorate>

Here is the processUpload method:

public void processUpload(UploadEvent event) {
     File attachedCopy = FileUpload.processUpload(event);
     this.getInstance().setAttachedCopy(attachedCopy);
}

after upload is complete, the fileUpload component should disappear and download button shoudl appear, but it is not happening.

Any tip?

Regards,
Chiara

I didn't try but maybe this works:

<s:decorate id="attachedCopyField" template="/layout/edit.xhtml">
     <ui:define name="label">Adjunto</ui:define>
     <rich:fileUpload id="notaAdjunta"
          rendered="#{outNoteHome.instance.attachedCopy == null}"
          fileUploadListener="#{outNoteHome.processUpload}"
          immediateUpload="true" ajaxSingle="true">
          <a4j:support event="onuploadcomplete"
                   reRender="attachedCopyField" />
     </rich:fileUpload>
     <s:button value="Download"
          rendered="#{outNoteHome.instance.attachedCopy != null}"
          action="#{fileDownloadBean.downloadFile(outNoteHome.instance.attachedCopy)}" />
</s:decorate>

I will try something else, but I don't know what could be happening.
