There are several ways of doing this. Chances are I am going to tell
you the "bad" ways, but others will jump in and suggest more correct
alternatives.
Method one is to create session objects (ones defined in your session
class) to store this information. You can then access and set these
from any of your pages. I would say to do this only if the information
really is related to a session (something that you want to have
globally available to all/most pages while that user is active.
Second option is to pass the data between pages. You can do this by the
following (skeleton help here):
In page A, have the data stored in local variables. In page B & C have
accessor methods and variables to hold a page object. When you are
ready to move on to page B, create it using pageWithName("B") and then
call setOriginalPage(A) - or whatever you called the accessor method
you created - before returning page B. This means that the new page B
will keep a reference to your first page A.
Do the same thing for travelling from B->C, passing page B to C. When
you want to return to B (and subsequently to A) instead of creating a
new page, just return the one stored in the variable. C will return the
B that you were previously in, and this B will hold and return the
original page A.
You should then have all your information they had previously entered.
Anyone else got other suggestions?
Ray.

I have a page A in which I enter few fields but will not save, instead
I will click on a button which will take me to a page B.I shall do
some transactions here which will load another page C and finally come
back to page B.Now I need to go from page B to page A on click of a
button/link.But now I cannot load page A by calling the method
"pageWithName("A");" , this will reload my entire page "A" again and I
will loose any information that I entered in "A" before.So is there
any way by which I can store the page "A" in some session/cache and
reload it again when i click on the link.Thanks in advance.
