Hi,
I recently updated to iBATIS 2.3 and it has broken my "complex" object
maps. Several searches on the mailing list indicate that this is a
problem but without a resolution or further research.
My basic problem: I have an "Image" object, that object has "sizes" and
"flags" properties, basically 1:M with "sizes" and 1:N with "flags". In
2.3, my "flags" relationship ends up being 1:N*M, in 2.1.7 (my last used
version) it was correctly 1:N.
My current workaround will be to downgrade to iBATIS 2.1.7
A short portion of my mappings follow:
<resultMap id="imageResult" class="Image" groupBy="id">
<result property="id" column="IMAGE_ID"/>
<result property="name" column="IMAGE_NAME"/>
<result property="description" column="IMAGE_DESCRIPTION"/>
<result property="owner.id" column="IMAGE_OWNER"/>
<result property="createTime" column="CREATE_TIME"/>
<result property="uri" column="IMAGE_URI"/>
<result property="orderMetric" column="ORDER_METRIC"/>
<result property="dimensions" resultMap="Images.dimensionsResult"/>
<result property="album.name" column="ALBUM_NAME"/>
<result property="album.description" column="ALBUM_DESCRIPTION"/>
<result property="album.id" column="ALBUM_ID"/>
<result property="album.uri" column="ALBUM_URI"/>
<result property="album.owner.id" column="ALBUM_OWNER"/>
<result property="flags" resultMap="Images.imageFlags"/>
</resultMap>
<resultMap id="dimensionsResult" class="Dimension" groupBy="id">
<result property="id" column="SIZE_ID"/>
<result property="description" column="SIZE_DESCRIPTION"/>
<result property="width" column="WIDTH"/>
<result property="height" column="HEIGHT"/>
</resultMap>
<resultMap id="imageFlags" class="Flag" groupBy="value,id">
<result property="id" column="FLAG_ID"/>
<result property="value" column="FLAG_VALUE"/>
</resultMap>
<select id="getById" resultMap="imageResult">

Thanks.
