Defaulting values in Process Request

Question

Hi,
I have a Search/Results page that goes to a detail page.
When the user first enters the form, I want to default date values (part of search criteria), so I included this logic in the Process Request section of the SearchCO.
The problem is, if the user changes the date value on the Search Screen, goes to the Detail screen, then returns to the Search Page via a 'link', the default logic in the Process Request kicks off again and overrides the date values the user entered.
How can I default these dates only the first time the user enters the form?
Thank you.

Thank you for your reply.
I was using a flag (tried declaring as Public Static as well as Private Static) outside the Process Request as below and it works great when I run it from JDeveloper, however, when I moved it to our development server, it only worked the first time I migrated it like it never reset the flag after leaving the form. I even logged right off and re-entered and the default logic still did not kick in.
public class OrderQueryCO extends OAControllerImpl
private static String firstTime = 'Y';
public void processRequest(OAPageContext pageContext, OAWebBean WebBean)
super.processRequest(pageContext, webBean);
if (firstTime = 'Y')
{ default date logic
* Procedure to handle form submissions for form elements in
* a region.
* @param pageContext the current OA page context
* @param webBean the web bean corresponding to the region
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
firstTime = 'N';
etc...
}
