Yeah, you are definitely doing something wrong. The problem in your case
is that you are using two different beans with different scopes. The
properties of the longer-than-request scoped bean are populated before
the action in your request scoped bean is executed, but you are likely
using the session scoped bean as a managed property of the request
scoped bean, and those instances are set when your request scoped bean
is created. The whole thing causes it to look like the propery updates
are coming in "late". One way to fix it is to move your search action to
the same bean as where your search properties are, which is a better
design anyway.
We have a similar page, but our search backing bean is request scoped,
and only the results are stored in the session scope with x:saveState.
