Re: [Wicket-user] Letting users download flat file
ResourceStreamRequestTarget implements IRequestTarget -- are you
suggesting that instead of instantiating an anonymous class that
implements IRequestTarget that I construct an instance of
ResourceStreamRequestTarget?
If so, its constructor requires an implementation of IResourceStream and
a string that contains the responseType. I suppose I could use
text/plain as the responseType, but where do I get the implementation
of IResourceStream? (That interface has a whole bunch of methods to
implement.)

you can use the ResourceStreamRequestTarget for that now and use
setFileName() for setting the filename.

Trying to adapt the code in DownloadLink, I came up with the
following event for my Button subclass:
public void onClick() {
getRequestCycle().setRequestTarget(
new IRequestTarget() {
public void detach(RequestCycle requestCycle) {}
public Object getLock(RequestCycle requestCycle) {
return null; }
public void respond(RequestCycle requestCycle) {

(WebResponse)requestCycle.getResponse();
r.setAttachmentHeader(myFilename.txt);
r.setContentType( text/plain; name=myFileName.txt );
PrintStream printStream = new
PrintStream(r.getOutputStream());
printStream.println(Line 1);
printStream.println(Line 2);}
}
);
}
I expect that when I run it and click the button, the browser
should pop-up a box asking me if I wish to save file myFileName.txt
-- a file that should contain two lines of text. But when I run
it and click my button, it goes back to the server, but then nothing
happens --the browser does not prompt me to save anything.
Do you see anything wrong with what I've done?

Re: [Wicket-user] Letting users download flat file
An text IResourceStream: StringBufferResourceStream
and i was looking ath the current 1.x svn and in that release the
constructor with the responseType is already depricated
and i think also setFilename isn't there yet.

set a breakpoint in respond() and see if it actually gets there, also try
printstream.close() at the end to flush the data
