Sven Boden commented on IBATIS-224:
-----------------------------------
Following "hack" in UnknownTypeHandler will make it work for IBATIS-224/210...
but is not available until Java 5 (1.5), and it also has some implications for
generics so I would suggest to put this JIRA and IBATIS-210 on the back-burner
for now. It will require some more thought:
public void setParameter(PreparedStatement ps, int i, Object parameter,
String jdbcType)
throws SQLException {
Class searchClass = parameter.getClass().getEnclosingClass();
if ( searchClass == null ) {
searchClass = parameter.getClass();
}
TypeHandler handler = factory.getTypeHandler(searchClass, jdbcType);
handler.setParameter(ps, i, parameter, jdbcType);
}
> isNotNull node causes typehandler mappings in statement to fail

> Here's my insert statement.
> <insert id="createDeployment" parameterClass="deployment">
> INSERT INTO Deployment (
> environmentId, deploymentTypeId, deploymentStatusId,
> deploymentTime
> <isNotNull
> property="threadCountOverride">,threadCountOverride</isNotNull>
> ) VALUES (
> #environmentId#, #deploymentTypeId#, #deploymentStatusId#,
> #deploymentTime#
> <isNotNull
> property="threadCountOverride">,#threadCountOverride#</isNotNull>

> <selectKey resultClass="int" keyProperty="deploymentId">
> SELECT @@IDENTITY as value
> </selectKey>
> </insert>
> deploymentTypeId and deploymentStatusId are enums in the bean, mapped to
> values using custom type handlers. Without the isNotNull structure around
> threadCountOverride (which *is* nullable), the statement works. With the
> isNotNull, deploymentStatusId and deploymentTypeId are mapped to
> UnknownTypeHandler, and the insert fails to map the parameters from the bean.
