Migration to 3.0

I'm in the process of migration to 3.0,
And I'm experiencing certain difficulties with understanding new submit mechanism.

For instance, In Xform I have something like:

  <xForms:submit>
         <xForms:label>Submit</xForms:label>
             <xForms:setvalue ref="/form/document/pcs:PCS/background/attachment/@id">
                <xsl:value-of select="/form/attachmentList/attachment/@id"/>
             </xforms:setvalue>  
             <xforms:setvalue ref="/form/action">save</xforms:setvalue>
  </xforms:submit>

And in pageflow:

  <action when="/form/action = 'save'   action="../PCSentry_DEV/detail/save-document-action.xpl">
       <result page="summary_DEV">
                .....

        </result>
  </action>

After :

I add the following line to my model:
<xforms:submission id="main-submission" method="post" ref="instance('main-instance')" action="xforms-upload" encoding="multipart/form-data"/>

And change the xform into:

<xforms:trigger>
    <xforms:label>Submit</xforms:label>
    <xforms:action ev:event="DOMActivate">
    <xforms:recalculate model="main-model"/>
    <xforms:send submission="main-submission"/>
    </xforms:action>
</xforms:trigger>

And I'm getting nothing in return. I press "Submit" button and nothing happens, of course.
My problem is, that I don't exactly understand what I am doing, simply copying code from different examples has lead me nowhere so far.

Kind regards,

-Taras

Here, it is important to understand what the "action" attribute means
on <xforms:submission>:

o That attribute is a URL (which may be relative).

o It is resolved according to xml:base attributes in the XForms page,
   if you have any, or (which is the usual case) to the *request*
   URL. E.g., if you access your page with:

   http://localhost:8888/ops/myapp/mypage

   you get as resolved action with the above:

   http://localhost:8888/ops/myapp/xforms-upload

o The resulting URL is used to perform a request. If the URL points to
   paths handled by OPS, your page flow must correctly handle the
   associated path. In this case, the path would be:

   /myapp/xforms-upload

So you must answer first the question: will that path do anything with
your current page flow?

Now you are of course 100% right in one aspect: the errors you are
getting are less than helpful. We are currently thinking about how we
can improve the developer's experience by providing an XForms console,
that would log events, allow you to visualize XForms intances and
MIPs, steps of submission, etc.

For now, there is a little bit of guess work required. Note that for
debugging, you can enable some XForms tracing in log4j.xml by
uncommenting the following:

     <category name="org.orbeon.oxf.xforms.processor.XFormsServer">
         <priority value="debug"/>
     </category>

In the case of submissions, you can also look in the logs at whether
there is a request made on OPS as a result of the submission. You can
also, under the <xforms:submission> element, place event handlers for
xforms-submit-error and xforms-submit-done, and use <xforms:message>
to display a different message in both cases, so that at leat you know
whether from the XForms engine's point of view the submission
succeeded or failed.

I hope this helps,

-Erik
