Ag InputCosts query return empty table

[rubcalvo]

Dear all, I'm trying to use a new query to extract Input Costs from the Ag Production module, but it results in an empty table.

  <aQuery>
  <all-regions/>
  <query title="ag tech input cost">
         <axis1 name="technology">technology</axis1>
         <axis2 name="Year">technology</axis2>
         <xPath buildList="true" dataName="inputCosts" group="false" sumAll="false">*[@type='sector' and (local-name()='AgSupplySector')]/*[@type='subsector']/*[@type='technology']/inputCosts/text()</xPath>
         <comments/>
  </query>
  </aQuery>

This query is based on one included in Main_queries.xml from GCAM Core that works fine.

  <aQuery>
  <all-regions/>
  <query title="ag tech variable cost">
         <axis1 name="technology">technology</axis1>
         <axis2 name="Year">technology</axis2>
         <xPath buildList="true" dataName="nonLandVariableCost" group="false" sumAll="false">*[@type='sector' and (local-name()='AgSupplySector')]/*[@type='subsector']/*[@type='technology']/nonLandVariableCost/text()</xPath>
         <comments/>
  </query>
  </aQuery>

Thanks in advance!
