SV: page refresh cleans my page state
Hi
I have gone through the HybridUrlCodingStrategy. The HybridUrlCodingStrategy is
working porperly in WebApplication but not in portal environment. In
WebApplication it retain the page state but not in portal environment.
Please suggest what should I do in portal environment.
Thanks in advance.

Re: page refresh cleans my page state
store the value on the session? make it a static member variable or store
it at application level? it all depends on what you want: the value to
change independently for each user or be the same for all users...
