Notification when file type rejected RF 4

[brabbit27]

Hallo !

   I've been using RichFaces 4 for a while for uploading files to a server. I saw that the rich:fileUpload component has the ability to accept or reject a file depending on the extension of the file.

    To make my webapp more user-friendly I would like to notify the user when a file was rejected. I see there's something like rich:notifyMessage component but I don't know how to make the notification globe appears when a file was rejected. I'm using ontyperejected event but still nothing appears on screen.

    It would be really nice to have a globe that appears and fades out just to give some feedback to the user. So far I have this:

    <rich:fileUpload id="fileUploadComp"
                     addLabel="Agregar" clearAllLabel="Quitar todos"
                     clearLabel="Quitar" deleteLabel="Quitar"
                     doneLabel="Completado" uploadLabel="Subir archivos"
                     fileUploadListener="#{uploadBean.doUpload}"
                     acceptedTypes="txt, csv" onclear="onclear(event);"
                     noDuplicate="true">
        <a4j:ajax event="uploadcomplete" render="validationButton"/>
        <a4j:ajax event="typerejected" render="notificationFileRejected"/>
    </rich:fileUpload>

    <rich:notifyMessage for="fileUploadComp"
                        id="notificationFileRejected"
                        sticky="true"
                        ajaxRendered="true"
                        title="Hello"/>

Any idea on how can I make this message appear?

Cheers

Well finally I found a solution.

<rich:fileUpload id="fileUploadComp"
                 addLabel="Agregar" clearAllLabel="Quitar todos"
                 clearLabel="Quitar" deleteLabel="Quitar"
                 doneLabel="Completado" uploadLabel="Subir archivos"
                 fileUploadListener="#{uploadBean.doUpload}"
                 acceptedTypes="txt, csv" onclear="onclear(event);"
                 ontyperejected="ontyperejected();"
                 noDuplicate="true">
    <a4j:ajax event="uploadcomplete" render="validationButton"/>
</rich:fileUpload>

<a4j:jsFunction name="ontyperejected" actionListener="#{uploadBean.setMessage()}"/>

<rich:notifyMessage stayTime="2000" nonblocking="true"/>

with the backing bean

public void setMessage() {
  String message="Wrong filetype...";
  FacesContext.getCurrentInstance().addMessage("info", new FacesMessage(FacesMessage.SEVERITY_INFO, message, message));
}

The only little problem I found in this is that If the user select the same file consecutively the message doesn't appear the second time. This is, select fileA.wrongType -> notification appears -> Select fileA.wrontType -> NO notification
