1) Again, replace the names of your form fields:
from: <s:textfield
name="#session.formBean.firstName"value="%{#session.formBean.firstName}"
label="First Name" size="16" />
to: <s:textfield name="formBean.firstName" label="First Name" size="16" />
2) SessionAware interface: it is pointless to implement it if you are
not going to save the session Map in an instance variable for future
reference, and if getting the session through Map session =
(Map)ActionContext.getContext().get("session"); works, it is not the
preferred way of getting it [1]
3) javascript code: Note that if the user press Enter key on a
textfield, the form will be submitted without assigning your target
hidden field.
