Hi Folks,
Probably im doing it wrong, but please bear with me, currently i'm trying to
do a very simple download operation in wicket 1.5M3, but it fails with a NPE
in (ResourceStreamResource.java line 72), because it seems is always
expecting that any IResourceStream implementation set the lastModifiedTime
in the underlying stream before calling dataNeedsToBeWritten which
StringResourceStream doesn't do it ( i need to explicitly set it to make it
work ) .
@Override
protected ResourceResponse newResourceResponse(Attributes attributes)
{
ResourceResponse data = new ResourceResponse();
(72)-> data.setLastModified(stream.lastModifiedTime().toDate());
My code using [StringResourceStream]
<code>
final StringBuilder content = new StringBuilder("Hello,world");
add(new Link<Void>("downloadDoc") {
@Override
public void onClick() {
StringResourceStream stream = new
StringResourceStream(content.toString(),"html/csv");
getRequestCycle().scheduleRequestHandlerAfterCurrent(new
ResourceStreamRequestHandler(stream)
.setFileName("demo.csv")
.setContentDisposition(ContentDisposition.ATTACHMENT));
}
});
</code>
Calling [stream.setLastModified(Time.now());] right before scheduling the
request handler make the download to works, but it seems that probably im
doing something wrong (not supposed to a download on this way) or does it
sounds like a bug in [ResourceStreamResource.java]?
Thanks,
Attached is a quickstart
