[daisy] Faceted browsing troubles

[Caleb Callaway]

Hi all,

I have a faceted browser setup on one of my Daisy sites. It was working
fine, until a recent upgrade to Daisy 2.2. When I click on a facet, it is
added to the filter correctly, but the document list isn't actually
filtered.

I haven't changed the definition at all, other than adding or removing
facets when attempting to troubleshoot the problem. Here's what it looks
like:

<facetedNavigationDefinition
xmlns="http://outerx.org/daisy/1.0#facetednavdef">
<optionsList defaultOptions="standard">
    <options id="standard">
      <limitToSiteCollection>false</limitToSiteCollection>
      <limitToSiteVariant>false</limitToSiteVariant>
      <defaultConditions>documentType = 'Part' or documentType =
'Assembly'</defaultConditions>
    </options>
  </optionsList>

  <facets>
   <facet expression="$Product"/>
  </facets>
</facetedNavigationDefinition>

No errors are reported, and I haven't found anything useful in the logs. I
haven't found any changes to the facet file definitions...any ideas?

Thanks,
-Caleb
