ADF - HierarchyViewer - Children not displayed

Question

Hello,
I want to use the ADF hierarchy viewer component. Following some tutorials on the net, I tried to realize mine.
1.I create the component from a VO (call it, DepartementsVO) with their children (call them ManagersVO and EmployeesVO).
2.I test, all datas are well displayed. I can collapse and expand all the nodes. It works :)
3.But there are too much data. So, I decide to set the "Descendent levels" attribute to 0. I reload the page. Only the root level is expanded. It works. :)
4.But when I click on the "expand" button, a blue ring appears and the component is disabled, the time to retrieve the data of the children (I think) but it is infinite. I have to reload the page to visualize the children datas. It does not work. :( The collapse works fine.
On step 4, I have no errors, no trace. The problem is on the client side perhaps. I used IE9 and Firefox 19. Do you have any idea on what is wrong ?
I am on jdev 11.1.2.2.0 and the component is displayed in a dynamic region.

Answer 1

After a day of test,
I got this behaviour when DepartmentVO has more of one child.
The case DepartmentVO -> ManagerVO is ok with descendent level set to 0.
The case DepartmentVO -> EmployeeVO is ok with descendent level set to 0.
But the case DepartementVO -> ManagerVO and EmployeeVO is KO with descendent level set to 0.
In the bindings of my page definition, I have two items in the accessors : ManagerVO and EmployeeVO.
>
<tree IterBinding="IlotsVO1Iterator" id="IlotsVO1">
<nodeDefinition DefName="com...DepartmentVO" Name="DepartmentVO10">
<AttrNames>
<Item Value="Id"/>
<Item Value="Name"/>
</AttrNames>
<Accessors>
<Item Value="ManagerVO"/>
<Item Value="EmployeeVO"/>
</Accessors>
</nodeDefinition>

When I delete one, by example ManagerVO, it works fine but the managers are no more displayed (logic).
It looks like a bug and I do not find a workaround for this.
