Subject: [ops-users] no result back to client after submission

Hai all out there,

I (still) have trouble giving back a result to the client after a submission...

First question is:
does anybody have an example of a form, that submits a part of the model via a pipeline to a custom java processor and than gives back a result (just a message is enough) to the client?
I think it should be possible (would be very weird if it is not possible, I think!) and if anybody knows how to do this, I think it should help if we make an example for it and add it to the xforms-sandbox...

I really think I just have a very small error in configuration somewhere and I cannot find what is going wrong. Here is what I have:

in my .xhtml:

            <xforms:instance id = "result-instance">
                <root>
                    <result/>
                    <failure/>
                    <success/>
                </root>
            </xforms:instance>

and

            <xforms:submission
                id = "mail-submission"
                ref = "instance('form-instance')/

formcontent"
                xxforms:show-progress = "false"
                method = "post"
                action = "/e-formulieren/mail"
                replace = "instance"
                instance = "result-instance">
                <xforms:setvalue ev:event = "xforms-submit-done" ref = "instance('result-instance')/success">success</xforms:setvalue>
                <xforms:message ev:event = "xforms-submit-error" level = "modal">error occurred</xforms:message>
            </xforms:submission>

in my page-flow.xml:
    <!-- mail -->
    <page path-info="/e-formulieren/mail" model="forms/xpl/mail.xpl" />

in forms/xpl/mail.xpl:

<p:config
    xmlns:p = "http://www.orbeon.com/oxf/pipeline"
    xmlns:oxf = "http://www.orbeon.com/oxf/processors"
    xmlns:xsl = "http://www.w3.org/1999/XSL/Transform"
    xmlns:divosa = "http://www.divosa.com/ops/processors">
    <p:param name = "instance" type = "input"/>
    <p:param name = "data" type = "output"/>
    <p:processor name = "divosa:mailProcessor">
        <p:input name = "data" href = "#instance"/>
        <p:output name = "data" ref = "data"/>
    </p:processor>
</p:config>

and then my mailProcessor:
public class MailProcessor extends SimpleProcessor {

    private static Logger LOGGER = Logger.getLogger(MailProcessor.class);

    public MailProcessor() {
        addInputInfo(new ProcessorInputOutputInfo("instance"));
        addOutputInfo(new ProcessorInputOutputInfo(OUTPUT_DATA));
    }

   
    @Override
    public void generateData(PipelineContext context, ContentHandler contentHandler) throws SAXException, DocumentException {
        Document inputDocument = readInputAsDOM4J(context, "data");
        if (LOGGER.isDebugEnabled()) {
            LOGGER.debug(inputDocument.asXML());
        }
       
        org.dom4j.Document doc = DocumentHelper.createDocument();
        org.dom4j.Element root = doc.addElement("root");
        org.dom4j.Element result = root.addElement("result");
        // do the actual processing on the submitted information
        try {
            FormSubmitHandler formSubmitHandler = FormSubmitHandlerFactory.getFormSubmitHandler(Constants.FORM_SUBMIT_MAIL);
            String r = (String) formSubmitHandler.handle(inputDocument);
            result.addText("Het formulier is succesvol gemaild op "
                    + new SimpleDateTimeFormatter("dd-MM-YYYY HH:mm:ss").formatSimpleDateTime(new DateTime()));
        } catch (Exception e) {
            result.addText("Er is een fout opgetreden bij het mailen: " + e.getMessage());
        }
       
        LocationSAXWriter saxWriter = new LocationSAXWriter();
        saxWriter.setContentHandler(contentHandler);
        saxWriter.write(doc);
    }

As you can see, with the declaration in the submission:
                replace = "instance"
                instance = "result-instance"
I try to replace the result instance with what I construct in the MailProcessor...

The logging put to debug, this is (all) what I see:
2009-09-01 09:52:20,055 WARN  XFormsServer  - XForms - submission - instance replacement did not take place upon successful response because no body was provided. Submission: mail-submission

Can you help??? Do you see where I go wrong?

And I really think it would help to add an example to the sandbox.. then I won't have to bother you about thiss...

Thanks and best regards,
