Description

Reported by a friend –

<dataConfig>
...
          <field column="Address"           xpath="/records/fullrecord_metadata/addresses/address_name/address_spec/full_address" />
          <field column="AddressALL"     xpath="/records/fullrecord_metadata/addresses flatten="true" />
...
</dataConfig>

This definition doesn't seem to be importing anything in Address field – everything is consumed by AddressALL.

I looked briefly at the implementation of XPathRecordReader and it seems it's greedy with respect to flattened tree nodes, assuming no other field extracts data from subnodes.

I think this is a bug (or is it by design)?
