Download txt file

Hi all,
I have a problem when I want to download a txt file from the server.

I have my data stored in a Label called “message”, using “Content_preformatted” to allow “\n” and “\t” in the label.
To download the file, the user must click on a “Save” button:

Button print = new Button("Save", new Button.ClickListener() {
            public void buttonClick(ClickEvent event) {

            	StreamSource source = new MyStringSource("Un document",message.getCaption());
                String filename = "equivalence_list.txt";
                StreamResource resource = new StreamResource(source,filename, getApplication());
                resource.getStream().setParameter("Content-Disposition","attachment; filename="+filename);

StringSource class is:

class MyStringSource implements StreamSource {
    String name; 
    String data = new String();
    public MyStringSource(String name, String data) 
    { = name; = data;

	public InputStream getStream() {
		ByteArrayInputStream foStream = new ByteArrayInputStream(data.getBytes());
        try {
            return foStream;
        } catch (Exception e) 
        return null;

The problem I have is that if I show the label on my window it appears with line breaks, but when I click on the “Save button”, the file created appears without the line breaks.

It’s the first time I’m developing a download button, so I thing that I’m doing silly errors somewhere in the code, but I’m not able to figure out what I’m doing wrong.

Thank you all in advance!
