Facing problem while using aggregate functions.

Question

I am trying to use aggregate functions such as sum, count in my CQL query.
It is not giving me an error but i am unable to get the correct output out of that.
Query is:
<?xml version="1.0" encoding="UTF-8"?>
<wlevs:config xmlns:wlevs="http://www.bea.com/ns/wlevs/config/application"
xmlns:jdbc="http://www.oracle.com/ns/ocep/config/jdbc">
<processor>
<name>APL_EFW_CostEvent_Processor</name>
<rules>
     <view id="CostEventView"
          schema="eventName eventType eventId opportunityStatusId opportunity_cost APL_Event_Inbound"><![CDATA[
               SELECT      X.eventName, X.eventType,
                    X.eventId, X.opportunityStatusId,
                    X.opportunity_cost,X.APL_Event_Inbound
                    from APL_EFW_Master_Inbound_Channel
                    XMLTable (
                         '/' PASSING BY VALUE APL_EFW_Master_Inbound_Channel.APL_Event_Inbound as "."
                    COLUMNS
                         eventId char(256) PATH 'fn:data(Event/EventHeader/eventId)',
                         eventName char(256) PATH 'fn:data(Event/EventHeader/eventName)',
                         eventType char(256) PATH 'fn:data(Event/EventHeader/eventType)',
                              opportunityStatusId char(256) PATH                               'fn:data(Event/ApplicationDataArea/opportunity/opportunity_details/opportunity_status)',
                              opportunity_cost char(256) PATH                               'fn:data(Event/ApplicationDataArea/opportunity/opportunity_details/opportunity_cost)',
                              APL_Event_Inbound xmltype path '/'
                    ) AS X
               ]>
     </view>
<query id="CostEventQuery">
          <![CDATA[
               SELECT
                    XMLELEMENT("opportunity",
                         XMLELEMENT("cost_opportunity",
                              XMLFOREST(X.opportunity_cost))) as APL_Event_Inbound
                         FROM CostEventView
                         MATCH_RECOGNIZE (
                         MEASURES
                              A.opportunity_cost as opportunity_cost
                              PATTERN (B A+) within 30000 milliseconds
                              DEFINE
                              A as sum(A.opportunity_cost)> 1000                    )
                    as X
          ]]>
          </query>
</rules>
</processor>
</wlevs:config>
The problem i am getting is when the value is getting compared with the opportunity cost rather than with the sum of oppCost
A as sum(A.opportunityCost)>1000
A as A.opportunityCost >1000
Both the cases are treated as same .

It would help if you could provide sample input data and associated output that illustrates the problem
