How is the bean declared in the page? Or, is it declared in one page and
used in another?

Where is it stored? Remember that there are 4 scopes (in increasing
order of specificity): application, session, request, and page. If your
page is looking in request scope, but the bean is in the session, it
won't be found. Or, alternatively, if you store a bean in the request
and issue a redirect, then the bean has likely been discarded.

You'll have to give us more details. Note that this is not a Struts
forum, though many of us (including myself) have Struts experience and
would be glad to help. Technically, you ought to start a new thread
since you're asking about a new subject (this helps people find answers
to their questions when searching the archives).

Could you also be experiencing session timeouts that aren't properly
handled? Does your application use any kind of authentication and
authorization? If not, you could easily be seeing visitors with expired
sessions accessing actions that expect the session to be in a certain state.

There are lots of ways to fix this kind of thing, but the remedies all
depend upon your requirements and application architecture.
