What do you mean with "After clearing chronik"? Does this mean that the session
cookie is lost after "After clearing chronik"?
You may take a look at the generated HTML:
Onclick=".....?wicket:interface=:5:.............:pdfIcon:pdf::ILinkListener::"
This refers to a version oft he page that is no longer valid after the session
is lost. Refreshing the page starts a new session and it works again.
You must (I don't know how at the moment) produce a sort of bookemarkable url
for this case I think. My guess would be to use a separate servlet for this.

Betreff: Re: Problems displaying a PDF from stream
Now it works with IE and this is most important thing. Thank you very much!
However the problem with Firefox remains. After clearing chronik while Pdf
document is open if I click the link comes "page expired", after refreshing the
main page with link if I click link again comes empty page.
