Re: Adding to response header (filename)?
I've changed it to that below, but still get 18:22:47,185 ERROR WebResponse:190 - Unable to redirect to: ?wicket:interface=:2, HTTP Response has already been committed. in the logs. Isn't this the same as what's in the link you posted? I can post all the code, but all it is is a Link inside a Form. The code before what I've posted below simple appends text to the out, which is a StringBuilder. This is the only part where I send the request. I'm using 1.3 Wicket, and Apache Tomcat 6, if that helps. SimpleDateFormat formatFile = new SimpleDateFormat(MM-dd-); ResourceStreamRequestTarget rsrt = new ResourceStreamRequestTarget(new StringResourceStream(out, text/csv)); rsrt.setFileName(export_ + formatFile.format(Calendar.getInstance().getTime()) + .csv); getRequestCycle().setRequestTarget(rsrt); Jan Kriesten wrote: hi, see here: http://www.nabble.com/Download-link-from-DynamicWebResource--tf4353363.html#a12404601 regards, --- jan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Justin Stanczak Stanczak Group 812-735-3600 All that is necessary for the triumph of evil is that good men do nothing.

Re: Adding to response header (filename)?
Well, I still don't see a way to get around this error. I'll have to
live with it for now until I can look into it deeper. Has anyone else
had this error?

Re: Yanıt: Re: Adding to response header (filename)?
That's what I used to use, but it gives the same error. Do you not get
the error in the logs. The error doesn't stop it from working, but I
still would like to do it correctly according to Wicket.

But you shouldn't call respond yourself. That's for Wicket to do. The
only thing you should do is the the request target on the request
cycle.

Re: Adding to response header (filename)?
What do you use for the export? You probably should use a resource.
For instance:
public class DiscountsExport extends WebResource {
public static class Initializer implements IInitializer {
public void init(Application application) {
SharedResources res = application.getSharedResources();
res.add(discounts, new DiscountsExport());
}
}
public DiscountsExport() {
setCacheable(false);
}
@Override
public IResourceStream getResourceStream() {
CharSequence discounts = DataBase.getInstance().exportDiscounts();
return new StringResourceStream(discounts, text/plain);
}
@Override

super.setHeaders(response);
response.setAttachmentHeader(discounts.csv);
