jasper report passing parameter from list index - jasper-reports

Question

I got a scenario where I need to pass jasper report parameter value from a list using index.
I have the following query executed in the jasper report, with the following parameters defined.
<parameter name="clientServiceIds" class="java.util.Collection"/>
<parameter name="trafficPeriod" class="java.util.Collection"/>
<parameter name="transactionType" class="java.util.Collection"/>
<parameter name="transactionStatus" class="java.util.Collection"/>
<parameter name="roamingPartners" class="java.util.Collection"/>
<parameter name="ages" class="java.util.Collection"/>
SELECT
CLIENT_CODE,
PARTNER_ORG,
PARTNER_CODE,
SERVICE_TYPE,
TP_ID,
TRAFFIC_PERIOD,
SETTLEMENT_TYPE,
SDR_NET,
TRAN_CURR_NET,
TRAN_CURRENCY_ID,
DUE_DATE,
TRANSACTION_TYPE,
STATUS,
NOTE_ID,
AGE
FROM vw_transaction_search
WHERE $X{IN, client_service_id, clientServiceIds}
AND $X{IN, PARTNER_SERVICE_ID, roamingPartners}
AND $X{IN, traffic_period, trafficPeriod}
AND $X{IN, transaction_type, transactionType}
AND $X{IN, status_id, transactionStatus}
AND AGE BETWEEN $P{param1} AND $P{param2}
Here ages is a list which I am passing to the report, which contains two values at index 0 and index 1. All parameters (paramValueMap) I am getting from an external system which i cannot modify,
JasperFillManager.fillReport(jasperReport, paramValueMap, connection);
so I am looking for a way to pass parameters param1 and param2 in my Jasper report SQL from my Collection ages, something like param1=ages.get(0) and param2=ages.get(1), so the SQL will be something like
...AND $X{IN, status_id, transactionStatus}
AGE BETWEEN $P{ages.get(0)} AND $P{ages.get(1)}
is there any way possible to achieve this?

I was able to crack this down by adding two additional parameters age1 & age2 and passing the value to the added parameters from the list here are the details.
<parameter name="trafficPeriod" class="java.util.Collection"/>
<parameter name="transactionType" class="java.util.Collection"/>
<parameter name="transactionStatus" class="java.util.Collection"/>
<parameter name="roamingPartners" class="java.util.Collection"/>
<parameter name="age" class="java.util.List" isForPrompting="false"/>
<parameter name="age1" class="java.lang.Integer" isForPrompting="false">
<defaultValueExpression><![CDATA[$P{age}.get(0)]]></defaultValueExpression>
</parameter>
<parameter name="age2" class="java.lang.Integer" isForPrompting="false">
<defaultValueExpression><![CDATA[$P{age}.get(1)]]></defaultValueExpression>
</parameter>
