position() function not working within @label of xforms control?

All,

I've been trying to retrieve the index of the current repeat, but am having some difficulties. I have attached the source code to demonstrate the problem.

These are the recomendations I were following:
http://mail-archive.objectweb.org/ops-users/2006-09/msg00197.html

Here is my view:
============
     <xhtml:head>
         <xhtml:meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
         <xhtml:title>Testing</xhtml:title>
         <xforms:model>                        
             <xforms:instance id="test">            
                <aspic:inputs>
                    <aspic:input>a</aspic:input>
                    <aspic:input>b</aspic:input>                   
                </aspic:inputs>
             </xforms:instance>           
         </xforms:model>
     </xhtml:head>
    <xhtml:body>       
        <xforms:repeat nodeset="instance('test')/aspic:input" id="test-repeat">       
            <xforms:input ref=".">               
                <xforms:label>
                      Index: <xforms:output value="index('test-repeat')"/>,
                      Position: <xforms:output value="position()"/>
               </xforms:label>
            </xforms:input>
            <xhtml:br/>
        </xforms:repeat>       
    </xhtml:body>
</xhtml:html>

The outcome from this is:
===========================
Index: 1, Position: 1
Index: 1, Position: 1

The EXPECTED outcome from this is:
===========================
Index: 1, Position: 1
Index: 1, Position: 2

Is this expected behaviour or a bug? If this is expected behaviour, how would you retrieve the current index from within a label in an xforms control?

Anyone else had this problem? Does anyone have a workaround?

Thanks!

Alternatively, try: <xforms:output
value="count(preceding-sibling::aspic:input) + 1"/>
