I (still) have trouble giving back a result to the client after a submission...
Please, forget all other things mentioned in this mail conversation, because I mostly resolved them, but this one is still hard to figure out.
I'm really desperate now, because if I don't fix this now, I'll be forced to drop using orbeon and advice my client to use something else. And I don't want that, because I came all this way...
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:
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,
