How to add column to result in simple service

[Zhavic Tomek]

Hi,

Is there a way to add column to result returned by "performFindList" in 
simple service?

I have this part in simple service getting data from 
"AcctgTransAndEntries" entity:
      
       ...
       ...
       <set field="input.entityName" value="AcctgTransAndEntries"/>
       <set-service-fields service-name="performFindList"     
map-name="input" to-map-name="lookupParams"/>
       <call-service service-name="performFindList" 
in-map-name="lookupParams" transaction-timeout="7200">
           <results-to-map map-name="result"/>
       </call-service>       

After this I get a  result and I want to loop through it and add field 
to each row,
but Idon't know how or if it is possible.

           <iterate entry-name="listItem" list-name="result.list">
                  <!-- somehow add new fields to listItem -->
           </iterate>

When I try to use  in loop this:
     <set field="listItem.newField" value="test value" type="String"/>

I got an error that field "newField" does not exist in entity 
"AcctgTransAndEntries" (and it's true :-) )

Thanks in advance.
