Bean Profile lost

Hi ,

I am developing a JSP Dynpage and use profile and bean to communicate between the jsp and the dynPage.

Everything works fine initially, all the events execute perfectly fine.

The problem occurrs, say for example the screen is kept idle for 10 miniutes and then i click on a Button, the control then goes to doProcessAfterInput(), in this method when I try to read the bean value from the profile i get it as null.

Do I need to set some parameter , which says that the bean should be stored in the profile for a particular amount of time ? Or some settings on the server to resolve this issue ?

Thanks in advance,

Vivek
