I use richfaces 4.3.2 final version in JBOSS 7.1

I need to initialize the FileUpload object with data stored in a database

I used the DATA attribute but it doesn't work :

--------------

view

---------------

<rich:fileUpload id="upload"

                     immediateUpload="false"

                     data="#{upload.files}"

                     addLabel="#{msgs.addLabel}"

                     clearAllLabel="#{msgs.clearAllLabel}"

                     clearLabel="#{msgs.clearLabel}"

                     serverErrorLabel="#{msgs.serverErrorLabel}"

                     deleteLabel="#{msgs.deleteLabel}"

                     doneLabel="#{msgs.doneLabel}"

                     sizeExceededLabel="#{msgs.sizeExceededLabel}"

                     uploadLabel="#{msgs.uploadLabel}"

                     fileUploadListener="#{upload.listener}">

        <a4j:ajax event="uploadcomplete" execute="@none" render="info"/>

    </rich:fileUpload>

-------------------------------

my bean :

--------------------------------

private ArrayList<Uploads> files;

the Uploads class does have NAME and DATA attributes

  public void setFiles(ArrayList<Uploads> files) {

        this.files = files;

    }

    public ArrayList<Uploads> getFiles() throws ErroNegocio {

        /* LOAD DATA FROM DATABASE */

        ContextoAplicacional ctx = getContextoAplicacional();

        if (files == null) {

            files = new ArrayList<Uploads>();

            files = Locator.getGereGeral(ctx).consultarTodos(ctx,getInfo().getOpeNumDoc(),getInfo().getOpeVerDoc());

        }

      /* END READING FROM DATABASE */

        return files;

    }

thanks in advance
