Question

I´m trying to re-enable the control button in a rich:uploadFile after upload the file.

I have:

<rich:panel id="fileuploader">
    <script type="text/javascript">alert("rendering");</script>
<rich:fileUpload fileUploadListener="#{fileUploadBean.listener}"
            maxFilesQuantity="1"   id="upload" autoclear="true"
            acceptedTypes="jpg, gif, png, bmp" >
            <a4j:support event="onuploadcomplete" reRender="fileuploader" />
    </rich:fileUpload>
    <a4j:commandButton value="reRender" reRender="fileuploader"/>
</rich:panel>

I put a Script to be sure the panel is re-rendering.
I read that you can reRender the uploadFile control, or refresh the whole page. After I upload the file, the controlButton gets disabled, and although I do a rerender with the commandButton, the control button is still disabled. But when I do a full refresh page, the control is ok.

Im using rich faces 3.3.3

Any help?

Thanks

[Edit]

I found the problem, but not the solution yet! I have a table with multiple rows so I have multiple rich:fileUpload’s. If I just show one row and it works.

I’ve faced the same problem, to solve it I rerendered the control, not a panel that holds it, I don’t know if this approach will work (but it does for me):

EDIT: Changed your code for mine, maybe there is a difference that I can’t see.

<rich:fileUpload id="fuArchivoExcel" maxFilesQuantity="1"
    listHeight="60px" listWidth="350px" immediateUpload="false"
    fileUploadListener="#{cargaDocumentoRequerido.subeArchivo}"
    addControlLabel="Seleccionar archivo" uploadControlLabel="Subir"
    clearAllControlLabel="Borrar archivos"
    clearControlLabel="Borrar archivo" stopControlLabel="Detener" autoclear="true">
    <f:facet name="label">
        <h:outputText value="Se han subido {_KB}KB de {KB}KB" />
    </f:facet>
    <a4j:support event="onuploadcomplete" reRender="fuArchivoExcel,pnlMensajesError"
        oncomplete="finCargaArchivo('#{cargaDocumentoRequerido.mensaje.idMensaje}', '#{cargaDocumentoRequerido.mensaje.descMensaje}')" />
</rich:fileUpload>

EDIT (based in comments)

When you use the <rich:fileUpload> inside a repeater like <rich:dataTable>, you should rerender the repeater component instead of the single component. This will solve your problem.
