Unable to access model input within view

I have a basic set up where the pageflow uses a model to pass information to a view to be used in the form.

My model extracts information from the database and places the information in an XML document to pass to the view. The model xml is received by the view, however, when trying to access it via xsl, I get an error that it is unable to load the document: input:instance.


<page id="theform" path-info="/myform" model="form-data.xpl" view="standard.xhtml"/>


.....
<xsl:template name="build">
<xsl:param name="position" select="doc('input:instance')/params/level"/>
......

According to http://www.orbeon.com/ops/doc/reference-page-flow#d6e2527, my view should have access to the data that is passed in via the model via input:instance. So why can't my xsl access it?

One possibly important note to make is that my view (standard.xhtml) contains the use of XBL components and it is within an XBL component that the 'build' template is being called.

If anyone sees what is wrong, or can tell me a different way to achieve this, I am all ears. Thanks in advance.

Almost. The "data" output of form-data.xpl will be accessible to your
XSLT view (I am assuming that standards.xhtml is an XSLT file) as the
input document of that transformation. So you you can just use
"/params/level" there, and there is no need to use the doc() function.

Alex,

Standards.xhtml is not exactly an XSLT file. It is an XHTML file that
uses multiple XBL components. Inside one of the XBL components, I use
transforms within the <xbl:template xxbl:transform="oxf:xslt"> statement.

In the XBL I have

<xbl:template xxbl:transform="oxf:xslt">
....
<xsl:call-template name="buildtree">
   <xsl:with-param name="position" select="/params/level"/>
</xsl:call-template>
...
</xbl:template>


Just using /params/level gets me past the error. However, the value of
position is nil. Do I still have the XML from the model as input to this
XSL? Or is it only the content of the XBL itself that is the input to
the XSL? I have to have the 'level' information, but am really stuck
with how to access it. The level information is stored within a file in
eXist, but at a location that would need parameters interpreted from the
URL (via page-flow) in order to locate the proper file. I have failed at
attempts to access the parameters interpreted from the URL within the
XSL too.
