How to load and pass a Xforms form in Orbeon (How to Send instance to XForms) ?

Answer 1

+1 A:

Only an xforms:submission replace="instance" makes sense when used from the oxf:xforms-submission processor. So the result from the submission must return XML, but this won't work here since when you do a submission to an XForms page, HTML is returned.

I assume that you have a form that does a submission replace="all" to /CUSDECCD001B/write. Instead:

Do submission replace="instance" and store the result in an instance.
In pipelineWrite.xpl return the file output of the Java processor directly, without calling the XForms submission processor.
Back in the XForms that does the submission replace="instance" to /CUSDECCD001B/write, when that submission is done (xforms-submit-done) run another submission that POSTs the results to /CUSDECCD001B/success.

Hi Alessandro. Thanks a lot for your help ! Actually you're right, I should have inserted the XForms code that start the whole process. So, I edited my post to add the "ViewModify" XForms page. Then I tried to apply the modifications you indicated. I think it's almost ok for the items 2/ and 3/ you listed, but last thing is that I don't see how to "store the result in instance" (item 1/).Could you have a look at the new versions of files ? Thanks a lot !

Clem, the code looks right. So I assume you also have an instance `CUSDECCD001BFile` (since you have `instance="CUSDECCD001BFile"` in the submission). If you don't you'll need to add one, and at first it can contain just about anything. I often put an element `<dummy/>` to make it clear this is just a placeholder.

Answer 2

A:

After taking Alessandro adivces into consideration and searching for other code snippets on Orbeon wiki, here is the solution that works fine for me :

The pipeline receiving a filled form instance on his instance input:

piplineWrite.xpl

<p:param name="instance" type="input"/>
<p:param name="data" type="output"/>

<p:processor name="oxf:java">
    <p:input name="config">
        <config sourcepath="." class="ProcessorWrite"/>
    </p:input>
    <p:input name="input" href="#instance"/>
    <p:output name="output" ref="data"/>
</p:processor>

The PFC catching actions and lauching the corresponding one :

page-flow.xml

<config xmlns="http://www.orbeon.com/oxf/controller"&gt;
    <page path-info="/CUSDECCD001B/write" view="Controller/PipelineWrite.xpl"/>
    <page path-info="/CUSDECCD001B/success" view="View/ViewSuccess.xhtml"/>
    <epilogue url="oxf:/config/epilogue.xpl"/>
</config>

The view Success receiving data output after processing :

viewSuccess.xhtml

<html ...>
  <head>
    <xforms:model>
        <xforms:instance id="FILE" src="input:instance"/>
    </xforms:model>
  </head>
  <body>

    <p> Generation Success !</p>

    <div class="toolbar">
        Cliquer to download :
        <xforms:output ref="//file" appearance="xxforms:download">
            <xforms:filename ref="@filename"/>
            <xforms:mediatype ref="@mediatype"/>
            <xforms:label>Download</xforms:label>
        </xforms:output>
    </div>
  </body>
</html>

The view Modify with a "Save" button lauching the whole process :

viewModify.xhtml

<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:xforms="http://www.w3.org/2002/xforms" xmlns:ev="http://www.w3.org/2001/xml-events"&gt;
  <head>
    <xforms:model>
      <xforms:instance id="CUSDECCD001BFile">
        <dummy xmlns="" />
      </xforms:instance>
      <xforms:submission id="save-submission" ref="instance('CUSDECCD001B')" action="/CUSDECCD001B/write" method="post" replace="instance" instance="CUSDECCD001BFile">
        <xforms:action ev:event="xforms-submit">
          <xforms:send submission="send-submission" />
        </xforms:action>
      </xforms:submission>
      <xforms:submission id="send-submission" ref="instance('CUSDECCD001BFile')" action="/CUSDECCD001B/success" method="post" />
    </xforms:model>
  </head>
  <body>
    ...
    <xforms:submit submission="save-submission">
      <xforms:label>Save</xforms:label>
    </xforms:submit>
  </body>
</html>

The main problems in the previous code snippet and advices given were :

the <xforms:instance> must specify a resource="" or at least contains a default content (here <dummy />),
the xforms-submit-done event doesn't seem to work or exist. So, I used an xforms-submit event.
