ADF Tree Target Data Source works badly(doesn't with certain circumstances)

Question

Hi OTN,
On my ADF page I have an af:TreeTable. It exposes 3 levels of hierarchy.
The DataModel is:
ComponentVO
- ParameterVO
- - IndexVO
All 3 are based on ComponentEO entity.
There are also 3 dependant tables on the page, which shows those 3 VOs.
I want the selection in tree to change current row in all three tables.
I'm trying to use Target Data Source feature in a tree binding.
For each level of the tree I specified a target data source like "${bindings.ComponentView1Iterator}".
Also added a partialTrigger attributes to tables to be refreshed upon tree selection.
At runtime I see this feature work almost good.
I click the tree nodes and see all three tables updating current row but there is a situation when they don't.
Say, we have a following node structure:
c1
- p1
- - i11
- - i12
- p2
- - i21
When I select i21 and trying to switch to i11 directly (without clicking p1) nothing happens.
It seems Target Data Source feature doesn't work on parent nodes having only one child.
I've tried removing PartialTriggers, changing ChangeEventPolicy... no luck.
Could someone help coping with the problem?
Thanks.

Here's tree binding:
<tree IterBinding="ComponentView1Iterator" id="TemplateTreeView1">
      <nodeDefinition DefName="model.view.ComponentView"
                      Name="TemplateTreeView10"
                      TargetIterator="${bindings.ComponentView1Iterator}">
        <AttrNames>
          <Item Value="Name"/>
        </AttrNames>
        <Accessors>
          <Item Value="ParameterView"/>
        </Accessors>
      </nodeDefinition>
      <nodeDefinition DefName="model.view.ParameterView"
                      Name="TemplateTreeView11"
                      TargetIterator="${bindings.ParameterView1Iterator}">
        <AttrNames>
          <Item Value="Name"/>
        </AttrNames>
        <Accessors>
          <Item Value="IndexView"/>
        </Accessors>
      </nodeDefinition>
      <nodeDefinition DefName="model.view.IndexView" Name="TemplateTreeView12"
                      TargetIterator="${bindings.IndexView1Iterator}">
        <AttrNames>
          <Item Value="Name"/>
        </AttrNames>
      </nodeDefinition>
    </tree>Edited by: ILya Cyclone on Apr 25, 2011 7:16 PM

Hi,
works fine for me. I created a tree and used the ChangeEvent policy on the referenced iterators.
