You should try downloading wicket's sources as suggested and placing breakpoint at EOFException. -Kirill On Wed, Jan 13, 2010 at 12:48 PM, Martin Asenov <mase...@velti.com> wrote: > Please, everyone, I'm really despaired about this one, I'll greatly > appreciate any help! > > Best regards, > > -----Original Message----- > From: Martin Asenov [mailto:mase...@velti.com] > Sent: Tuesday, January 12, 2010 4:37 PM > To: users@wicket.apache.org > Subject: RE: page expired problem issue wicket how resolve fix > eofexception > peekbyte > > Thanks a lot for your time, Chuck! > > I hope others will join our conversation... > > Regards, > > -----Original Message----- > From: Chuck Brinkman [mailto:chasb1...@gmail.com] > Sent: Tuesday, January 12, 2010 3:57 PM > To: users@wicket.apache.org > Subject: Re: page expired problem issue wicket how resolve fix > eofexception > peekbyte > > Martin, > > I was not suggesting a permanent change to the framework.
