Form inputs are populated by the PopulationStrategy.
DefaultPopulationStrategy, which you are probably using right now, populates
an input's value first from a request parameter having the same name as the
input, if any, then from the (nested) property of the form's ActionBean, and
finally from the "value" attribute.
You can change to BeanFirstPopulationStrategy to reverse the first two. That
is, the value will be pulled first from the ActionBean property then from
the request parameter then from the "value" attribute. To switch the whole
application to bean-first, add the following to your StripesFilter
configuration:
<init-param>
<param-name>PopulationStrategy.Class</param-name>
<param-value>net.sourceforge.stripes.tag.BeanFirstPopulationStrategy</param-value>
</init-param>
In my opinion, the default strategy is the better one. Bean-first can be
useful sometimes, as in this case. Ideally, one would be able to switch
between the two as needed. Such a strategy is described here
