When using returnfields in an ecogrid query, the original xpath used in the returnfield is not returned with the results, making it very difficult to parse the results. When a query is submited, a ResultsetTypeRecordReturnfield object is returned. This object only has two useful methods: get_value() and getId(). I thought getId() would return the original xpath query used to create the returnfield, but instead it returns a cryptic identifier starting with 'f' then a number.

Example:
Given these returnfields:
<returnField>/entity/@name</returnField>
<returnField>/entity/property/@name</returnField>
<returnField>/entity/property/@value</returnField>

And this input document:

<entity name="Variable Setter" class="ptolemy.kernel.ComponentEntity">
<property name="entityId" value="urn:lsid:kepler-project.org:actor:10:2"
class="org.kepler.moml.NamedObjId"/>
<property name="documentation" class="org.kepler.moml.DocumentationAttribute">
null
</property>

<property name="class" value="ptolemy.actor.lib.SetVariable" 
            class="ptolemy.kernel.util.StringAttribute">
    <property name="id" value="null" 
              class="ptolemy.kernel.util.StringAttribute"/>
  </property>

<property name="kepler:input" class="org.kepler.moml.PortAttribute">
    <property name="direction" value="input" 
              class="ptolemy.kernel.util.StringAttribute"/>
    <property name="dataType" value="unknown" 
              class="ptolemy.kernel.util.StringAttribute"/>
    <property name="isMultiport" value="false" 
              class="ptolemy.kernel.util.StringAttribute"/>
  </property>

<property name="variableName" class="ptolemy.kernel.util.StringAttribute" 
            value="parameter">
  </property>
  <property name="delayed" class="ptolemy.data.expr.Parameter" value="true">
  </property>
  <property name="semanticType000" class="org.kepler.sms.SemanticType" 
            value="urn:lsid:localhost:onto:1:1#Variable">
  </property>
  <property name="semanticType111" class="org.kepler.sms.SemanticType" 
            value="urn:lsid:localhost:onto:2:1#LocalInput">
  </property>
  <property name="_location" class="ptolemy.kernel.util.Location" 
            value="{250, 300}">
  </property>
  <property name="karId" class="ptolemy.kernel.util.StringAttribute" 
            value="urn:lsid:kepler-project.org:kar:11:1">
  </property>
</entity>

You will get returnfields (in the format getId():get_value()) like this:
returnfield: f0:Variable Setter
returnfield: f1:entityId
returnfield: f2:urn:lsid:kepler-project.org:actor:10:2
returnfield: f1:documentation
returnfield: f1:class
returnfield: f2:ptolemy.actor.lib.SetVariable
returnfield: f1:kepler:input
returnfield: f1:variableName
returnfield: f2:parameter
returnfield: f1:delayed
returnfield: f2:true
returnfield: f1:semanticType000
returnfield: f2:urn:lsid:localhost:onto:1:1#Variable
returnfield: f1:semanticType111
returnfield: f2:urn:lsid:localhost:onto:2:1#LocalInput
returnfield: f1:_location
returnfield: f2:{250, 300}
returnfield: f1:karId
returnfield: f2:urn:lsid:kepler-project.org:kar:11:1

Instead, there either needs to be a new method, getQuery(), that would return the query for each field, or the getId() should return the query or some other more meaninful identifier.
