Description

I'm trying to use the following resultMap:

<resultMap type="ACE" id="aceMap">
<result property="actorName" column="actorName"/>
<result property="isGranted" column="isGranted"/>

<association property="permission" javaType="Permission">
<constructor>
<idArg column="permissionId" javaType="int"/>
<arg column="permissionName" javaType="String"/>
</constructor>
</association>
</resultMap>

The constructor of "Permission" takes int (primitive type) and String as parameter. This results into the following Exception when iBATIS tries to instantiate the object:

1. 1. 1. Error querying database. Cause: org.apache.ibatis.executor.ExecutorException: Error getting nested result map values
         for 'permission'. Cause: org.apache.ibatis.reflection.ReflectionException: Error instantiating class com.brainware.gb.security.Permission with invalid types (Integer,String,) or values (0,READ,). Cause: java.lang.NoSuchMethodException: com.brainware.gb.security.Permission.<init>(java.lang.Integer, java.lang.String)
      2. The error may involve com.brainware.gb.security.db.internal.SecurityMapper.getACEs-Inline
      3. The error occurred while setting parameters
      4. Cause: org.apache.ibatis.executor.ExecutorException: Error getting nested result map values for 'permission'. Cause: org.apache.ibatis.reflection.ReflectionException: Error instantiating class com.brainware.gb.security.Permission with invalid types (Integer,String,) or values (0,READ,). Cause: java.lang.NoSuchMethodException: com.brainware.gb.security.Permission.<init>(java.lang.Integer, java.lang.String)

         ...

The problem seems to be that iBATIS tries to find a constructor with java.lang.Integer, not for the primitive type.
