Problem passing XML data with XUpdate in page-flow.xml

Hello everyone,

Like many others, I am trying for the first time OPS and am quite new to
XSLT, XPath, Xforms.. stuff. I checked the tutorial with the bizdoc
application and I am trying to replicate it with a simple form. I got
some problem though passing xml data with XUpdate in the page flow xml
file. I can't retrieve the data in my XForm. Problem could be somewhere
else (namespace?) but that is my guess for now.

Here are my entries in page-flow.xml:

<config xmlns="http://www.orbeon.com/oxf/controller"
xmlns:oxf="http://www.orbeon.com/oxf/processors"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xu="http://www.xmldb.org/xupdate"
instance-passing="forward">


<page id="bloggers"
path-info="/beelog"
xforms="bloggers/bloggers-xforms.xml"
view="bloggers/bloggers-view.xsl"
model="bloggers/bloggers-model.xpl"
>


<action when="/form/action = 'show-post'"
action="oxf:/beelog/bloggers/find-post-action.xpl">
<result page="post">

<xu:update select="/form/post">
<xu:copy-of select="doc('input:action')/post/*"/>
</xu:update>
</result>
</action>
</page>

<page id="post"
path-info="/beelog/post"
xforms="oxf:/beelog/post/post-xforms.xml"
view="oxf:/beelog/post/post-view.xsl"
/>


<page id="home" path-info="/">
<action>
<result page="bloggers"/>
</action>
</page>

<epilogue url="oxf:/config/epilogue.xpl"/>

</config>

The post-xforms.xml file:

<?xml version="1.0" encoding="utf-8"?>
<xforms:model
xmlns:xforms="http://www.w3.org/2002/xforms"
xmlns:post="http://www.evision.ca/oxf/demo/beelog/post"
xmlns:xi="http://www.w3.org/2001/XInclude"
>
<xforms:instance>
<form>
<action/>
<xi:include href="../schema/post.xml"/>
</form>
</xforms:instance>
<xforms:submission method="post"/>
</xforms:model>

The post.xml file:

<post xmlns="http://www.evision.ca/oxf/demo/beelog/post">
<rant/>
</post>

The post-view.xsl file:

<html xsl:version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xforms="http://www.w3.org/2002/xforms"
xmlns:ev="http://www.w3.org/2001/xml-events"
xmlns:xxforms="http://orbeon.org/oxf/xml/xforms"
xmlns:post="http://www.evision.ca/oxf/demo/beelog/post"
xmlns:xhtml="http://www.w3.org/1999/xhtml"
xmlns="http://www.w3.org/1999/xhtml"
>
<body>
<div class="content">
<xforms:group ref="/form">
<xforms:repeat nodeset="post:post">
<xforms:output ref="post:rant">
<xforms:label>Rant</xforms:label>
</xforms:output>
</xforms:repeat>
</xforms:group>
</div>
</body>
</html>

I know my find-post-action.xpl sql processor works because when I use
this in my page flow:

<page id="post"
path-info="/beelog/post"
view="oxf:/beelog/bloggers/find-post-action.xpl"
/>

It returns me the expected xml, i.e.:

<post xmlns="http://www.evision.ca/oxf/demo/beelog/post">
<rant>First post to this blog built using XForms, XSLT, XML and plenty of other friends.</rant>
<rant>First post to this blog built using XForms, XSLT, XML and plenty of other friends.</rant>
</post>

OPS doesn't give me any error, data just isn't showed. I am sure I'm
missing something simple. Can anyone help me?

RE: Problem passing XML data with XUpdate in page-flow.xml

Jimmy, in your XSL form, your referencing a group ref of /form, but the
returning XSL doesn't have a form tag, nor does it have a post namespace!

Re: Problem passing XML data with XUpdate in page-flow.xml

Hi, thx Ryan for the fast answer,

The page-flow.xml file has an xforms attribute targeting to
post-xforms.xml in which the form tag is. I understand from the bizdoc
example that this XForms should be used with the view.

<page id="post"
path-info="/beelog/post"
xforms="oxf:/beelog/post/post-xforms.xml"
view="oxf:/beelog/post/post-view.xsl"
/>

The post namespace is in my post-view.xml file (from the header):

<html xsl:version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xforms="http://www.w3.org/2002/xforms"
xmlns:ev="http://www.w3.org/2001/xml-events"
xmlns:xxforms="http://orbeon.org/oxf/xml/xforms"
xmlns:post="http://www.evision.ca/oxf/demo/beelog/post"
xmlns:xhtml="http://www.w3.org/1999/xhtml"
xmlns="http://www.w3.org/1999/xhtml"
>

Ok. After more testings I am able to retrieve the data through the
XForm. I had to add the namespace in the XUpdate, resulting in the
following action tag in my bloggers page:

<action when="/form/action = 'show-post'"
action="oxf:/beelog/bloggers/find-post-action.xpl">
<result page="post">
<xu:update select="/form/post:post"
xmlns:post="http://www.evision.ca/oxf/demo/beelog/post">
<xu:copy-of select="doc('input:action')/post:post/*"/>
</xu:update>
</result>
</action>

Quite strange that the bizdoc example works without specifying the
'claim' namespace. Maybe I did something else. One question though.. If
in my page-flow.xml I put..

<page id="post"
path-info="/beelog/post"
view="oxf:/beelog/post/post-view.xsl"
xforms="oxf:/beelog/post/post-xforms.xml"
model="oxf:/beelog/post/find-post-action.xpl"
/>

.. so that data of my page doesn't rely upon another page action (no
redirection). Will the data output of my find-post-action.xpl sql
processor will copy itself into the xforms? Or I have to do it manually
through XSLT or XUpdate? Because as the above my data doesn't seem to go
into the post-xforms.xml XForm.

Well I guess its time for me to read more documentation. :)

Hi Jimmy,

You might already know this, but I feel like I have to start by saying
that you are using here the XForms Classic engine. This an engine that
is backward compatible with the engine in PresentationServer 2.8 and
earlier. Unless you have a specific reason to use it, I recommend you
use current engine: XForms NG. To use XForms NG, you should not have
the XForms model referenced with the xforms="..." attribute in the
page flow, but instead put the XForms model in the view.

With XForms Classic, which you are using, if you want to update the
instance in the model, you need to feed the new document you want to
be used as the new instance to the "instance" output of the model.

Hi Alessandro,

I didn't know that the xforms attribute was deprecated and that it leads
to the use of the XForms Classic engine.. I went through the tutorial
with the bizdoc application that make use of it. I guess that's why I
can't find the bizdoc example on the OPS website anymore. I will look on
a more recent example then!

Thanks a lot,
Jimmy

RE: Problem passing XML data with XUpdate in page-flow.xml

Jimmy,
I believe the DMZ Forms is a good one to use as it is one of the
newer ones and covers a fair bit of the engine, like bizdoc did!

Jimmy,

Exactly: the "DMV Forms" is a new example that replaces the old
"BizDoc". And the tutorial has not been updated for PresentationServer
3.0. We still need to update it and we'll maybe end up mostly
rewriting it. In the meantime, the examples, the documentation, and
this list (!) are the best places to look at.
