How NOT to execute the custom type handler in a resultMap?

[berms]

Hi all. I am currently converting an ibatis code to mybatis and I am
using the MapperFactoryBean on mybatis.

I have a custom type handler called CurrencyAmountTypeHandler. The
handler simply set and get a BigDecimal. I defined it in the config
xml as:

<typeHandler javaType="my.package.CurrencyAmount"
handler="my.other.package.CurrencyAmountTypeHandler" />

Then in one of my mapper, I have this:

<resultMap id="currencyAmountMap" type="my.package.CurrencyAmount">
        <result property="amount" column="amount"
javaType="java.math.BigDecimal"/>
        <result property="exchangeRateUsd" column="exchange_rate_usd"
javaType="double"/>
        <association property="currency" select="getCurrencyByCode"
column="budget_currency"/>
    </resultMap>

The query looks like this:

 <select id="getContribTotals" parameterType="map"
resultMap="currencyAmountMap">
        SELECT  NVL(SUM(I.TOTAL_AMOUNT), 0) as amount,
                'USD' as budget_currency,
                1.0 as exchange_rate_usd
        FROM    ...
    </select>

After executing the query, I noticed that it is going to the
CurrencyAmountTypeHandler. Maybe because I have a
type="my.package.CurrencyAmount" in the resultMap?

Is there a way not to execute the CurrencyAmountTypeHandler using the
above configurations?

Thanks.
Mike
