Don't specify value. Simply copy the properties from a subscriber
object (session scoped or otherwise) to a formbean (the one being used
to render the form values). There's a copyProperties method in
org.apache.commons.beanutils.BeanUtils:

Also, the Spring Framework has a copyProperties method in one of its
utility classes. It has the advantage of not throwing a checked
exception and its parameter ordering makes more sense to some (myself
included).
A reason to not specify a value for html:text, at the view level, is
that it overwrites the value in an associated form-bean object. This
could lead to overwriting user input or overwriting data that was
populated from an Action.
It may be acceptable to specify value on a checkbox, for instance,
because user's don't typically interact with this value directly.
Still, if a value for a checkbox, like any other form control, was set
in a controller class, then a page level value will overwrite data. At
the very least, this is counterintuitive. More often, it is incorrect.
