[orbeon-user] xxforms:if problem

[Matthew J. Graham]

Hi,
I have the following in my search-view.xsl:
      <xxforms:if test="count(/form/constraint) &gt; 1">
        <xforms:submit>
          <xforms:label>AND</xforms:label>
        </xforms:submit>
      </xxforms:if>
The AND button will only show if there is more than one  
/form/constraint (this is all enclosed in a xforms:repeat on the  
/form/constraint nodeset).

The error thrown is:
org.dom4j.InvalidXPathException: Invalid XPath expression:  
/form/constraint[1]/count(/form/constraint) > 1 Expected node-type

Any ideas?
        Cheers,
