Thank you. I hope this helps. As I was waiting for the reply, I found out the get() can be used with the combination of PreviousPage. but the problem with that is the data from one page can be accessed only on the immediate next page. But According to you suggestion, the data can be used anywhere within the applicaion..
If you put it into the session, you can grab it anywhere yes. If you put it on the form, you will need to retrieve it from the form values and place it onto the next form ad infinitum until you need to use it.
Either way is acceptable really, but if you want to use it throughout the application, it would be better sitting in Session.
