Subject RE: Checking radio button based on object value
Date Thu, 02 Dec 2004 18:14:43 GMT
Ok so I've tried the following but still I get the default values on the
form when it's forwarded to the JSP.

<action path="/options"
        type="ie.sentenial.application.actions.UserAction"
        name="optionsForm"
        scope="request"
        input="/templates/optionsForm.jsp"          
        attribute="optionsForm" >
</action>

My action class has the following:

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
IOException, ServletException 
{

if(request.getParameter("action").equals("useroptions"))
{
	// set the options form values to those of the current user
	ClientOptionsForm optionsForm = setOptions(request); 

	form = (ClientOptionsForm) optionsForm; 
	return(mapping.findForward("viewoptions"));
}

The saving part of the action works fine, all the new values overwrite the
old. The problem is still showing the previously chosen values upon viewing
the JSP.

Any help would be appreciated.
Thanks

Struts handles the creating of the form for you.  You should not be
"creating" a form nor "storing it" in the session scope.

Look at the parameters on your Action's execute.  There is a
"ActionForm form" -- you cast that form to your form's type:

MyFormClass myform = (MyFormClass) form;

then you manipulate it's properties.  You don't have to put it back in
the session -- it exists in the request scope and is managed by
struts.
