iBATIS Parameter Maps (a.k.a my iBATIS brain f*rt)

Problem:
On a project using iBATIS, I was receiving the following stacktrace:

stacktrace

org.springframework.dao.TransientDataAccessResourceException: SqlMapClient operation; SQL [];  
--- The error occurred in {myproject}/PlanningProject.xml. 
--- The error occurred while applying a parameter map. 
--- Check the {myparametermap}  
--- Check the parameter mapping for the 'startDate' property.  

--- Cause: java.sql.SQLException: Parameter index out of range (1 > number of parameters, which is 0).; nested exception is com.ibatis.common.jdbc.exception.NestedSQLException:   
--- The error occurred in com/kpe/resourcePlanning/domain/dao/ibatis/PlanningProject.xml. 
--- The error occurred while applying a parameter map. 
--- Check the {myparametermap}  
--- Check the parameter mapping for the 'startDate' property.  
--- Cause: java.sql.SQLException: Parameter index out of range (1 > number of parameters, which is 0).

And this is the snippet of the parameter map that is significant:

PlanningProject.xml

  <parameterMap id="updatePmap" class="PlanningProject">
    <parameter property="startDate" jdbcType="TIMESTAMP" javaType="org.joda.time.LocalDate" typeHandler="com.kpe.resourcePlanning.domain.dao.ibatis.TypeHandlerCallbackLocalDate" />
    <parameter property="endDateConstraint" jdbcType="TIMESTAMP" javaType="org.joda.time.LocalDate" typeHandler="com.kpe.resourcePlanning.domain.dao.ibatis.TypeHandlerCallbackLocalDate" />     
    <parameter property="modifiedBy" jdbcType="VARCHAR" />
    <parameter property="id" jdbcType="NUMBER" />
  </parameterMap>

  <update id="update" parameterMap="updatePmap">
    UPDATE resourcePlanning.planningproject
    SET 
        startDate = #startDate#,
        endDateConstraint = #endDateConstraint#,
        modifiedBy = #modifiedBy#,
        modifiedDate = now() 
    WHERE 
        projectId = #id#
  </update>

Well, my project hardly ever used explicit parameter maps. Usually, statements used the parameterClass="" syntax. So, as you might already know, my syntax was terribly wrong. The correct syntax follows. The thing to note (at least for me) is that the order of the individual SET parameters must match the order given in the parameter map that you use.

  <parameterMap id="updatePmap" class="PlanningProject">
    <parameter property="startDate" jdbcType="TIMESTAMP" javaType="org.joda.time.LocalDate" typeHandler="com.kpe.resourcePlanning.domain.dao.ibatis.TypeHandlerCallbackLocalDate" />
    <parameter property="endDateConstraint" jdbcType="TIMESTAMP" javaType="org.joda.time.LocalDate" typeHandler="com.kpe.resourcePlanning.domain.dao.ibatis.TypeHandlerCallbackLocalDate" />     
    <parameter property="modifiedBy" jdbcType="VARCHAR" />
    <parameter property="id" jdbcType="NUMBER" />
  </parameterMap>

  <update id="update" parameterMap="updatePmap">
    UPDATE resourcePlanning.planningproject
    SET 
        startDate = ?,
        endDateConstraint = ?,
        modifiedBy = ?,
        modifiedDate = now() 
    WHERE 
        projectId = ?
  </update>
