Hello,
I do have a problem with I think the Ajax stuff I sent in my
previous e-mail.
I changed the progressbar example a bit so an ajaxform with
an ajax submit button appears after the task is completed.
Then I would like to serve data (that was created during the
progressbar action) as a file.
I implemented a service which works if called from a normal
submitButton (I get a file).
But from the Button within this ajaxform I get no reponse in my
browser, although the method seems to execute fine .
What is wrong there and how can I achieve what I would like
to have?
Thank you very much for your answers.

public void service(IRequestCycle arg0) throws IOException {
writeFile(request, response);
}
public void writeFile(HttpServletRequest request,
HttpServletResponse response) {
try {
response.setHeader("Cache-Control",
"must-revalidate, post-check=0,
pre-check=0");
response.setHeader("Pragma", "public");
response.setHeader("Content-disposition", "inline;
filename="
+ "test.tsv");
response.setContentType("text/tab-separated-values");
String text = "hello world";
PrintWriter writer;
try {
writer = response.getWriter();
writer.write(text);
writer.close();
response.flushBuffer();
System.err.println("called streamResult");
} catch (IOException e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
