replace getRequestCycle().scheduleRequestHandlerAfterCurrent

2015-01-26 Thread Roland Dobsai 
Hi we're using getRequestCycle().scheduleRequestHandlerAfterCurrent,
various places in our application which causes 500 error, is there any we
to replace, lines  below because my solution which is:
String url = RequestCycle.get().urlFor(rs).toString();
  throw new RedirectToUrlException(url);
doesn't work.

///
ResourceStreamRequestHandler rs = new ResourceStreamRequestHandler(
new StringResourceStream(work, text/csv));
rs.setFileName(Workdone_ +
projectModel.getObject().getName().replaceAll([^a-zA-Z0-9], ) + .csv);

this.getRequestCycle().scheduleRequestHandlerAfterCurrent(rs);

or another example I was trying to replace

ResourceStreamRequestHandler rs = new ResourceStreamRequestHandler(new
FileResourceStream(new File(file.getAbsolutePath(;
  rs.setFileName(df.getFileName());
this.getRequestCycle().scheduleRequestHandlerAfterCurrent(rs);

with this, but doesnt work either:
String url = (RequestCycle.get().urlFor(rs)).toString();
   throw new RedirectToUrlException(url);

thanks for any help

 Hi,

 Error 500 means that there must be an exception in the logs. What is it ?

 What exactly doesn't work means in your case ? Another exception, or
 no-op behavior, or ... ? Please give more details.

Wicket by default buffers the write/flush of the markup to the browser
until the end of the the request cycle.

The exception says that the application has already written some
bytes/characters to the browser and it is not possible to make a redirect,
because the response headers are already sent.

Put a breakpoint at RelativeUrlServletResponseFilter#write() methods and
see when and why it is being called earlier.

It seems we cannot reproduce this locally - only in production. Difference
being apache is in front of tomcat. If we comment out the following code we
have no issues:


setPageRendererProvider(new IPageRendererProvider() {
@Override public PageRenderer get(final RenderPageRequestHandler
context) {
   return new WebPageRenderer(context) {
 @Override protected RedirectPolicy getRedirectPolicy()
{
   RedirectPolicy result;
if (!((WebRequest)
RequestCycle.get().getRequest()).isAjax()  (context.getPage() instanceof
ExternalShareSecurePage || context.getPage() instanceof
ExternalShareDocumentPage)) {
  result =
RedirectPolicy.NEVER_REDIRECT;
   } else {
 result = super.getRedirectPolicy();
   } return result;
  }
  };
  }
 });
