Hi Leonid,

In JSF all selects are validated against bean model and if there are submitted items that are not present in the model, validation fails due to security reasons. If you are absolutely sure that it's ok, then just build up select model from submitted data.

Hi Leonid,

Whether JSF needed or not depends on current project business requirement specification...

So, how could I pass them back to the server to build up select model? Could you provide some example?

You can create afj:jsFunction, and call it in you javascript method (where you have a functionality of getting filenames...), by passing needed data as method param, e.g. you can construct any String with specified format (delimetered by commas "filename1, filename2,....") and further get separated filenames in server side business logic....

Here is similar functional from one of my projects:

<a4j:jsFunction name="showMonth"
                        reRender="fusMonthChrt"
                        actionListener="#{metricsController.initMonthlyChart}"
                        oncomplete="changeWindowPosition();">
                <a4j:actionparam id="reportYearParam" name="reportYear"/>
                <a4j:actionparam id="reportTypeParam" name="reportType"/>              

</a4j:jsFunction>

.................................

function showChartByGivenParams(year, type)
    {

        ..............

       showMonth(year, type);             
    }

................................

/**
     * Action Listener method, called when user clicks on
     * any column in yearly Fusion Chart.
     * @param event
     */
    public void initMonthlyChart(ActionEvent event) {

          ............................

          FacesContext.getCurrentInstance().getExternalContext().getRequest().getParameter("reportType");

          ..............................

    }
