Re: At what point in the cycle does struts fill out the ActionForm

[Simon Kelly]

Hi Nicolas and Andrew,

Thanks for the two mails.

Here is what I do in the Action class

[code]
<!-- I get the form from the execute() parameter list -->
SignalSelectForm currentForm = (SignalSelectForm) form;

<!-- Some other bits I need that were set when the user logged into the
site -->
String uri = (String)session.getAttribute(KatrinConstants.DATABASE_URI);
String name = (String)session.getAttribute(KatrinConstants.USER_NAME_TAG);
String passwd =
(String)session.getAttribute(KatrinConstants.USER_PASSWD_TAG);
Document dbstruct =
(Document)session.getAttribute(KatrinConstants.DB_TABLES_DATA);

<!-- I put the form into the request like I would normally do -->
 request.setAttribute(StrutsCXConstants.CURRENTFORM, currentForm);

<!-- This is the business logic section I use to extract the form info.
        The code in here is identical to the code in the servlet. -->
RequestSignalsDelegate rsd = new RequestSignalsDelegate();
<!-- Here is where I first try to use the form data
        I am sending the request as I know it should
        be in here. -->
ArrayList signalVOs = rsd.createSubsystemList(request);
SignalSelectXML ssxml = new SignalSelectXML();
Document results = ssxml.getSignalData(uri, name, passwd, signalVOs,
dbstruct);

request.setAttribute(StrutsCXConstants.XML_KEY, results);
request.setAttribute(StrutsCXConstants.XSL_KEY, xslfile);
request.setAttribute(StrutsCXConstants.XML_DEBUG_PARAM,
StrutsCXConstants.TRUE);

return mapping.findForward(StrutsCXConstants.FORWARD_SUCCESS);
[code]

The servlet it forwards to is a bit big, so I've not included it. But the
code in the servlet to extract the form information, is identical to the one
in the RequestSignalsDelegate and it removes the form from the request in
the same way as well.

Thanks again for your help.

Cheers

Simon
