JBO-25058 exception when running adf:tree component

Question

Hi, I was trying to prototype an adf:tree which uses eo, vo, and view links as a data model. I am trying to use the vo recursively.
Data model consists of :
EO: PeggingDataEO
VO: TopPeggingDataVO
PeggingDataVO
View Links: TopToFirstLevelVL (source: TopPeggingDataVO, destination: PeggingDataVO)
ParentToChildVL ( source: PeggingDataVO, destination: PeggingDataVO)
When i ran this page, i get the root node , and then when I try to expand it , i get this error:
oracle.jbo.NoDefException: JBO-25058: Definition PeggingDataVO of type Attribute not found in TopPeggingDataVO_PeggingDataVO_TopToFirstLevelLVL_PeggingDataVO
This is build using JDeveloper 11g ( jdev fusiondrop306).
Please help. I don't understand what definition is missing and what TopPeggingDataVO_PeggingDataVO_TopToFirstLevelLVL_PeggingDataVO is?
Thanks
-c.
below is the code for the page definition :
<executables>
<iterator Binds="TopPeggingDataVO1" RangeSize="25"
DataControl="AppModuleDataControl"
id="TopPeggingDataVO1Iterator"/>
</executables>
<bindings>
<tree IterBinding="TopPeggingDataVO1Iterator" id="TopPeggingDataVO1">
<nodeDefinition DefName="recursivetree.datamodel.queries.TopPeggingDataVO">
<AttrNames>
<Item Value="InventoryItemName"/>
<Item Value="SourceType"/>
<Item Value="SupplyDemandDate"/>
<Item Value="SupplyDemandQuantity"/>
<Item Value="ParentPeggingId"/>
<Item Value="PeggingId"/>
</AttrNames>
<Accessors>
<Item Value="PeggingDataVO"/>
</Accessors>
</nodeDefinition>

Hi,
can you run the VO in the tester ? The error message often indicates that the database connection uses a wrong schema
