The FormBeanConfig object provides access to the createActionForm() method. That's the object you actually need.

In the example I gave, this would be the /submitForm action. In a setup action, this mapping may not be available or may be referring to a different form altogether. > Also, using > > request.getSession().setAttribute("myForm", myForm); > > is exactly the issue.

Struts uses session scope by default, which is why that's what I mentioned first. You can choose to use request scope. hth, Hubert > > > -----Original Message----- > From: Hubert Rabago [mailto:[EMAIL PROTECTED] > Sent: Friday, March 11, 2005 9:36 AM > To: Struts Users Mailing List > Subject: Re: Correct Prepopulate Method > > You would usually do prepopulation in a setup form.
