[Xsltforms-support] Odd behaviour with xf:itemset and XPath predicate

[Grégoire C. <gco...@gm...>]

Hi,

I've put a "xml:lang" attribute on my main model, as :

    <xf:model id="modele-recherche-requete">
      <xf:instance>
        <search xmlns="" xml:lang="en">
          <type/>
          <what/>
          <where/>
        </search>
      </xf:instance>
      <xf:submission id="submit" action="recherche.xql" method="get" />
    </xf:model>

What I want to do is to use the attribute's value in the "<search>" element
to retrieve the corresponding strings in my other model, as :

    <xf:select1 ref="/search/type" appearance="full" incremental="true">
      <xf:label><xf:output
ref="instance('instance-types-d-annonce')/resource[@xml:lang=*
/search/@xml:lang*]/label"/></xf:label>
      <xf:hint><xf:output
ref="instance('instance-types-d-annonce')/resource[@xml:lang=*
/search/@xml:lang*]/hint"/></xf:hint>
      <xf:itemset model="modele-types-d-annonce"
nodeset="instance('instance-types-d-annonce')/resource[@xml:lang=*
/search/@xml:lang***]/item">
        <xf:label ref="label"/>
        <xf:value ref="value"/>
      </xf:itemset>
    </xf:select1>

This works for the <xf:label> and <xf:hint>, but not for the <xf:itemset>
element (the list remains at "Loading..."). Please note that hard-coding the
language works, as in :

      <xf:itemset model="modele-types-d-annonce"
nodeset="instance('instance-types-d-annonce')/resource[@xml:lang=*'fr'***
]/item">

Why is the <xf:itemset> element in any way different from <xf:hint> or
<xf:label> regarding XPath? Any help would be kind as I'm out of ideas on
this one.

Regards,
Grégoire
