> Hi!
> I would like to know is there a way to stop fileUploadListener (fileUpload
> component) and diplay error message?
> E.g.
> I would like to upload file only if file with sam name doesn't egsist on
> server. It would be nice if the validation would be on client side. So I
> tried to do validation inside of fileUploadListener, but the message
> (<rich:messages />) is not shown, although the upload is stopped, and message
> is added.
> Is this a bug, or am I doing something wrong? Here is the code
> public void processUpload(UploadEvent event) {
>
> UploadItem item = event.getUploadItem();
> java.io.File f = item.getFile();
>
> fileList = getFiles();
> for (File file : fileList) {
> if(item.getFileName().equals(file.getName())){
> FacesContext ctx =
> FacesContext.getCurrentInstance();
> //Show message
> ctx.addMessage(null, new
> FacesMessage(FacesMessage.SEVERITY_ERROR,
> "error", "error"));
>
> ctx.renderResponse();
> return;
> }
> }
> //If file doesn't egsists...
