Try invoking with formfillin.html?Seminartitel=pass

This line will show you the generated html plus everything else:
javascript
:'<html><head><title>SourceFileListing<\/title><\/head><body><c
ode><ol><li>'+(document.documentElement||document. body).innerHTML.replace
(/&/g,"&").replace(/</g,"<").replace(/%20%20/g," %20").replac
e(/\r\n/g,"<li>").replace(/\n/g,"<li>").replace(/\r/g,"<li>")+'<\/ol><\/c
ode><\/body><\/html>';
It wrapped! In IE, you can change innerHTML to outerHTML.
