You need to use the form which is passed in from the execute() method signature.
DynaForm dForm = (DynaForm) form; dForm.set("author", "test"); return mapping.findForward("success"); This assumes you are using the same form for your setup and processing action and you are forwarding to the page which renders the form. robert > -----Original Message----- > From: Alexander Czernay [mailto:[EMAIL PROTECTED] > Sent: Wednesday, November 17, 2004 6:22 AM > To: Struts Users Mailing List > Subject: Prepopulate a DynaForm > > > I'm trying to prepopulate a DynaForm with some values - right now just > hard-coded, later should be taken from a DB.
