Dozer - Excluding nested Objects

According to this example you can do Deep Mapping with Dozer :

http://dozer.sourceforge.net/documentation/deepmapping.html

> <mapping>
> <class-a>com.github.dozermapper.core.vo.deep.SrcDeepObj</class-a>
> <class-b>com.github.dozermapper.core.vo.deep.DestDeepObj</class-b>
> <field>
> <a>srcNestedObj.src1</a>
> <b>dest1</b>
> </field>
> <field>
> <a>srcNestedObj.src2</a>
> <b>dest2</b>
> </field>
> <field>
> <a>srcNestedObj.srcNestedObj2.src5</a>
> <b>dest5</b>
> </field>
> </mapping>

Similarly I want to exclude few nested objects and fields, and so I tried same way :

> <mapping map-id="case1" map-null="false">
> <class-a>com.server.dal.entities.ClassA</class-a>
> <class-b>com.server.dal.dto.ClassB</class-b>
>
> <field-exclude>
> <a>childObj1.childObj2</a>
> <b>childObj1.childObj2</b>
> </field-exclude>
> <field-exclude>
> <a>childObj1.childObj3.testMap</a>
> <b>childObj1.childObj3.testMap</b>
> </field-exclude>
> </mapping>

But this is not working as expected. Is there any other way how to exclude nested Object's fields?

You can exclude nested objects as follows :

> <mapping map-id="caseClassA" map-null="false">
> <class-a>com.server.dal.entities.ClassA</class-a>
> <class-b>com.server.dal.dto.ClassB</class-b>
> <field map-id="excludeSubItem1">
> <a>childObj1</a>
> <b>childObj1</b>
> </field>
> </mapping>

> <mapping map-id="excludeSubitem1" map-null="false">
> <class-a>com.server.dal.entities.ClassChild1</class-a>
> <class-b>com.server.dal.dto.ClassChild1</class-b>
> <field-exclude>
> <a>childObj2</a>
> <b>childObj2</b>
> </field-exclude>
> <field map-id="excludeSubItem2">
> <a>childObj3</a>
> <b>childObj3</b>
> </field>
> </mapping>

> <mapping map-id="excludeSubitem2" map-null="false">
> <class-a>com.server.dal.entities.ClassChild3</class-a>
> <class-b>com.server.dal.dto.ClassChild3</class-b>
> <field-exclude>
> <a>testMap</a>
> <b>testMap</b>
> </field-exclude>
> </mapping>
