Error when reading policy cost by period query

[klau506]

Hey!

I'm getting an error when running the query policy cost by period. In the Model Interface it runs correctly, but in the R session, I obtain the following error, either using the runQuery or addSingleQuery function:

About to perform query: collection()/scenario

[basex:error] java.lang.ArrayIndexOutOfBoundsException: 0
Rows: 0 Columns: 0

The query I'm reading is extracted from the Main_queries.xml file:

   <aQuery>
      <all-regions />
      <costCurveQuery title="policy cost by period">
         <axis1 name="region">Curve</axis1>
         <axis2 name="Year">DataPoint</axis2>
         <xPath buildList="true" dataName="Cost" group="false" sumAll="false">PointSet/DataPoint/y/text()</xPath>
         <comments />
      </costCurveQuery>   
   </aQuery>

This happens regardless of whether the query is empty or not.

Thank you so much,
Clàudia
