Yo ho ho
Following the caffine finally kicking in at the end of my last e-mail I
added this code to the top of my Action class (that exends
DispatchAction).
This seems to work, it checks for the existance of the parameter named
in the mapping - if its null it will call the dispatchMethod with my
"init" which calls the init method, otherwise it goes on normally...
Does anyone wiser than me see issues with doing this?
------------------------------------------------------------------------
------
public ActionForward execute (ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException, Exception {
ActionForward af = null;
HttpSession session = request.getSession();
if (request.getParameter(mapping.getParameter()) == null) {
af = dispatchMethod (mapping, form, request, response,
"init");
}
else
{
af = super.execute (mapping, form, request, response);
}
return (af);
}

H'Okay...
* I've tried simply adding in another action called startPremadeReports
that forwards to: premadeReports.do?action=init
Problem is that the premadeReports has validation which fails because
you have not been to the form yet
* I've tried a globalForward but that has the same problem...
* The only thing that works so far is to have a whole different action
that is exactly the same without validation. then I am back to needing
the action=init on the first call.
I would really prefer not to hack the source code for a default setting,
but know that I am thinking about it, can I override the execute method
or something to check for the parameter, set a default if there is not
one there and then forward on to the super.execute method? Hmmmmmmmm

Perhaps you could save us the effort of suggesting things you have
already tried by telling us what you have tried? :-)
