JSP, getting Master-Detail to work

Question

JDeveloper 3.2.3
JSP, getting Master-Detail to work
- I've made a project with a master table Dept and a detail table Emp via the wizards. Automatically views for both are made.
- Secondly i created an association between Dept and Emp (based on the field Deptno), the association is exposed to both entities.
- I followed the Help example 'Creating Maser-Detail JSP Pages Using Data Web Beans'.
4 Data Web Beans are created with this example
* NavigationBar Master
* ViewCurrentRecord Master
* NavigationBar Detail
* RowSetBrowser Detail
The resulting JSP page shows, unfortunately, no link between the master and the details.
For one department all employees (of all departments) are shown.
What do i have to do to make the JSP Master-Detail work with JDeveloper
Thanx in advance

I resolve my problem to create a third level detail as viewobject as a own instance, without link to second level detail (as I supposed it to work). And manually make a new search with where clause inside working detail iterate loop (below).
I still wonder, is there any way to automatically update second details current row, which might also update third level details information as sophisticated way?
my solution to show third level in master-detail-detail information.
inside first details loop...
<jbo:ApplicationModule id="MyService" definition="DataBindings.MyServiceDataControl" releasemode="Stateless"/>
<%-- search criteria from detail --%>
<c:set var="whereLauseIn" value="MYKEY_ID = '${Row['secondId']}'" scope="page" />
<jbo:DataSource id="Lausu" appid="MyService" viewobject="ViewObjMyThirdDetailInst" whereclause="<%=pageContext.getAttribute(\"whereLauseIn\")%>" rangesize="-1"/>
<jbo:RowsetIterate datasource="Lausu" changecurrentrow="true">
<tr>
<td >
<jbo:ShowValue datasource="Lausu" dataitem="Col1" ></jbo:ShowValue> 
</td>
<td>
<jbo:ShowValue datasource="Lausu" dataitem="Col2" ></jbo:ShowValue> 
</td>
<td>
<jbo:ShowValue datasource="Lausu" dataitem="Col3" ></jbo:ShowValue> 
</td>
<td >
<jbo:ShowValue datasource="Lausu" dataitem="Col4" ></jbo:ShowValue> 
</td>
</tr>
</jbo:RowsetIterate>
<jbo:ReleasePageResources />
