Hi
I'm having problems mapping to a property which is a Set of java5 enums.
I have a class CounterpartyHedgeVO which has the property creditEvents which
is a Set<CreditEventEnum>.
Not sure what the problem is but I'm guessing that iBATIS tries to treat the
Enum like a POJO and fails to create it since there isn't a public
constructor. Or?
Any help would be really appreciated.
My current sqlmap (omitted the typeAlias definitions):
<resultMap class="CounterpartyHedgeVO" id="CounterpartyHedgeVOResult"
groupBy="refNo">
<result column="POS_RefNoADB" jdbcType="VARCHAR" property="refNo"/>
<result column="PRT_Code" jdbcType="VARCHAR" property="prtCode"/>
<result column="RBE_CodeCpty" jdbcType="VARCHAR"
property="counterpartyCode"/>
<result column="POS_Tradebook" jdbcType="VARCHAR"
property="tradeBook"/>
<result resultMap="CDS_HEDGE.CreditEventEnumResult"
property="creditEvents"/>
</resultMap>
<resultMap class="CreditEventEnum" id="CreditEventEnumResult">
<result column="CRE_EventType" property="value" jdbcType="VARCHAR"
typeHandler="hedge.dao.CreditEventEnumReadOnlyTypeHandler"/>
</resultMap>
