Problem with the XInclude processor

Hello,

I have a fairly simple pipeline setup :

<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">

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

  <p:processor name="oxf:xslt">
    <p:input name="data" href="ligne.xhtml"/>
    <p:input name="config" href="suggestion_template.xsl"/>
    <p:output name="data" id="ligne" debug="true"/>
  </p:processor>

  <!-- XSLT output contains xi:include elements -->

  <p:processor name="oxf:xinclude">
    <p:input name="config" href="#ligne"/>
    <p:output name="data" ref="data" debug="true"/>
  </p:processor>

</p:config>


However, the second transformation fails... with a NPE and an empty
error message !

java.lang.NullPointerException
        at org.orbeon.oxf.processor.xinclude.XIncludeProcessor$XIncludeContentHandler.startElement(XIncludeProcessor.java:160)
        at org.orbeon.oxf.xml.SAXStore.replay(SAXStore.java:162)
...

What is strange is that :
 - the first transformation works well for sure (checked from the debug output)
 - if I feed the XSLT output result to the XInclude processor 'config'
as inline content (instead of using #ID), everything works correctly !

Any idea ?

Oh, by the way, I tried with the lastest OPS from CVS and there is
still the same issue.

Thanks a lot,

Damiano,

How old is your build? I think this bug may have been fixed a couple of
weeks ago. It occurred when the source did not provide a system id,
which is the case of a document dynamically produced by XSLT.

Well, I build a new WAR file from a CVS checkout today and I still
have the same issue.

My mistake, it works indeed in newer builds.
Hum, now I'd like to xi:include the "data" output of the XPL model in
the 2nd transformation of my XPL view.
How can I do that ?

Cheers,

If you refer to my first message, you can see my XPL view.
And I have a XPL model for this page that has a "data" output,
querying a DB, which I'd like to use to populate an XForms instance
created by my view.

So I thought, let's Xinclude it in the second "step" of my pipeline,
with something like "<xi:include href='input:data'/>" -- which doesn't
work.

I suppose I have to change the
  <p:param type="input" name="instance"/>
to
  <p:param type="input" name="data"/>
in my XPL view to match the XPL model output ?

But, as I am no XPL expert, I didn't find a solution.

So, in last resort, I populated my instance with the XSLT processor --
via a quite horrible hack (?) I must say :/

My question amounts to ask : is it possible to access the XPL model's
"data" output in the XInclude processor call (according to my setup) ?

Hope, I am a bit clearer now -- I doubt anyway :)

Now I have a new problem -- still related to XInclude though.
I have a certain <p:when> branch of an <p:switch> that I'd like to
reuse in several XPL model files.
So I tried to use XInclude -- my old friend by now :-)

In my XPL model file :

    ...
    </p:when>

        <xi:include href="maj-informations.xml" xxi:omit-xml-base="true"/>

    <p:when>
    ...

which links to this content :

    <p:when xmlns:p="http://www.orbeon.com/oxf/pipeline"
            xmlns:xdb="http://orbeon.org/oxf/xml/xmldb"
            xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
            xmlns:oxf="http://www.orbeon.com/oxf/processors"
            test="//form/head/action = 'maj-informations'">
      <p:processor name="oxf:xslt">
      ...
      </p:processor>
    </p:when>

At first, it seemed to work but in fact it chokes on the processor name :

     Cannot find processor factory with name "xslt"

It looks like the "oxf:" prefix is mangled in the XInclude process.

Damiano,

There is no such p:switch it is a p:choose which takes an input of @href

If you have a p:choose containing all the same p:when then you could just
use the oxf:pipeine processor and pass the input for the p:choose into the
pipeline and return the output from the p:choose

If not then how are you making the call to run the choose? Are you taking
the output from the xinclude into the oxf:pipeline processor because this
should take the oxf namespace from the file your using

Perhaps you could share a bit more of the code?

Yes, indeed the element is named "choose" -- programming language habit !

Alright, so I have several pages. Each of them is associated with an
.xpl model file, with a <p:choose> containing several <p:when>. And
I've a got a few <p:when> which are common to all my pages. That's why
I'd like to XInclude them from a static XML file.

So, as I wrote in my previous message, in addition to "page-specific"
<p:when> child elements, all the <p:choose> would contain :

<xi:include href="maj-informations.xml" xxi:omit-xml-base="true"/>

to include a <p:when> contained in "maj-informations.xml".

That amounts to something like <http://pastebin.ca/95261>,
XInclude'ing <http://pastebin.ca/95265>.

Is it clearer now ?

Thanks for helping me BTW,

Damiano,
        what I mean is can you share the model.xpl code? That creates the
p:choose and processes it?

Well, my model.xpl is what I gave in <http://pastebin.ca/95261>
previously, with <http://pastebin.ca/95265> being the XML fragment
that I'd like to XInclude.

But maybe I don't really understand what you're asking me :-)

Cheers,

Declaring the 'oxf' prefix in the file that does the <xi:include>

Unfortunately, the 'oxf' prefix was *already* declared in the "parent"
file -- in both files actually. So the problem must come from
somewhere else...

Anyway, I have "refactored" my code, so I don't XInclude anymore in my
XPL files.

Hi Damiano,

OK, thank you for the update. If the problem happens again, you might
want to look into isolating the part of the files that seem to cause
the problem and attach to an email the files we need to reproduce the
issue.

Well, the issue is quite easy to reproduce : in any .xpl file, just
try to XInclude an XML file containing a <p:processor> definition.
You'll get the error, for example :

  Cannot find processor factory with name "xmldb-query"

When of course, in the included file, it's written <p:processor
name="oxf:xmldb-query"...>
Which tells me, as I said before, that the problem is related to the
'oxf' prefix somehow.

Damiano,

Indeed, I was able to reproduce that. I created a entry in the tracker
and attached the files I used to reproduce the error.
