Can someone enlighten me as to why when I instantiate a new ActionForm, the
old data seems to hang around? Here is the information:
I have a session scoped action form defined in struts config:
<action name="WidgetForm" path="/widget" scope="session"
type="com.mystuff.WidgetAction" validate="false">
<forward name="Add" path="AddWidget.pg"/>
etc, etc,
</action>
My dispatch method looks something like this:
public ActionForward addNewWidget(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse
response) {
form = new WidgetForm();
((WidgetForm) form).setMode(Constants.MODE_INSERT);
return mapping.findForward(Constants.ADD);
}
Assume that prior to adding a new widget, the user has already edited an
existing one, so the session-scoped WidgetForm is populated with the edited
widget's info.
After the addNewWidget() method is called and the user is sent to the add
page, the previous edited widget's data still displays. Why is this? Doesn't
the line "form = new WidgetForm();" wipe out the old object?
Essentially, I just want an empty WidgetForm when the user wants to add a
new widget. I was hoping not to have to write a "clear" method for all of my
session scoped ActionForms. I'm sure there's a simple solution, please
enlighten me.
(I hope the syntax is correct above. I was typing from memory. I don't have
the code here in front of me.)
Thanks,
