Subject RE: Checking radio button based on object value
Date Thu, 02 Dec 2004 14:59:54 GMT
Thanks for your replies.

I followed your suggestions, now I create a form in my action class, set its
values based on the session object, store it in session scope and forward to
the JSP but the form produced has the default values of my action form
instead of the values in the form object I have created. Any ideas why this
happens?

Thanks

Simple... in the action that forwards to the jsp.... you do have an action
forwarding to the jsp right? :)
Something like
	if( object in session) {
		copy object to form;
	}
	forward to jsp
