Define your form in struts-config.xml like:
<form-bean
name="mySearchForm"
type="org.apache.struts.action.DynaActionForm">
<form-property
name="sort"
initial="postDate"
type="java.lang.String"/>
<form-property
name="order"
initial="DESC"
type="java.lang.String"/>
.. Other properties here
</form-bean>
Then define your action mapping to use this formbean. When your form posts,
it will assume the default values for sort/order if they not present in the
request. If they're present in the HttpRequest object, then the form is
populated with whatever values are coming from the request.
Hope this helps.

Subject: The Same Action With and Without a Form
I have a "list" of articles to be retrieved from the
database and displayed.
The first time I display the list, I simply sort the
list by posting date and descending order (without
providing a form) when I query the database.
Thereafter, users are offered opportunities on top of
the table of the list to choose 'sort' criteria from a
drop down menu and to choose 'order', which is either
ascending or descending, with a GO button. That is to
say, the same action (ListArticles) is called with a
'form' consisting of two menus.
In my Java class that extends Action, I did the
following:
String sort = request.getParameter( "sort" );
String order = request.getParameter( "order" );
if ( sort.length() == 0 ) sort = "PostDate";
if ( order.length()== 0 ) order = "DESC";
I do not know how to handle the name attribute of the
<action .... /> tag in the struts-config.xml.
Those are the same action. There is actually an empty
form the first time the action is called. And there
is a form consisting of two menus the second time the
action is called.
I need your instructions and help.
