DIH - duplicate xpaths on HttpDataSource

[Erik Hatcher]

I'm trying to index a blog with DIH, and have this:

            <field column="id" xpath="/rss/channel/item/link"/>
            <field column="url" xpath="/rss/channel/item/link"/>
If I comment out the url <field> line it all works fine, but if I put  
it in, no documents get indexed.  Is there an issue with using the  
same xpath twice?   Or something else I'm missing?

This is using Solr trunk.

Thanks,
        Erik
