ADF Tree row selection and af:commandLink

Question

Hello,
I'm quite new to JDeveloper and ADF. I'm using JDev 11.1.1 and get some issues while trying to set up a "qualifications" selection tree. Here is a summary :
I'm dealing with "Qualification" objects. A qualification has an id,name and 'selected' attribute. A Qualification can contain a list of subqualifications (same type 'Qualification'), and so on, with no limits of levels. I would like to display this structure as a tree with, for each (sub-)qualification a selectbox showing the status (selected or not) and modifiable by the user.
The qualifications are exposed to the data controls through a ResourceManager class function getQualifications(), and the datacontrol is dropped as a tree in the jsf page. The tree is bind to a backing bean 'qualificationManagerBean', and i've added an ActionListener to handle node selection (set node as current row and call update action)
page definition :
<executables>
<accessorIterator MasterBinding="ResourceManagerIterator"
Binds="qualifications" RangeSize="25"
DataControl="ResourceManager"
BeanClass="com.mobileit.planning.web.Qualification"
id="qualificationsIterator"/>
</executables>
<bindings>
<tree IterBinding="qualificationsIterator" id="qualifications">
<nodeDefinition DefName="com.mobileit.planning.web.Qualification">
<AttrNames>
<Item Value="name"/>
<Item Value="selected"/>
</AttrNames>
<Accessors>
<Item Value="subqualifications"/>
</Accessors>
</nodeDefinition>
</tree>
</bindings>
</pageDefinition>
in the jsf page :
<af:form>
<af:tree value="#{bindings.qualifications.treeModel}"
binding="#{qualificationManagerBean.tree}" var="node">
<f:facet name="nodeStamp">
<af:commandLink text="#{node}" id="test"
actionListener="#{qualificationManagerBean.clickTree}">
<af:setActionListener from="#{qualificationManagerBean.tree.rowKey}"
to="#{qualificationManagerBean.clickedNodeRowKey}"/>
</af:commandLink>
</f:facet>
</af:tree>
</af:form>
The result is that tree is well displayed, but only the first level of the tree triggers the 'clickedNodeRowKey' and 'clickTree' action. When i click on sub-levels, the page gets submitted but actions are not called.
I've also tried to map the action to a method in my ResourceManager but the result is the same, action gets never called :
page def file :
<methodAction id="qualificationSelector" RequiresUpdateModel="false"
Action="invokeMethod" MethodName="qualificationSelector"
IsViewObjectMethod="false" DataControl="ResourceManager"
InstanceName="ResourceManager.dataProvider">
<NamedData NDName="ref"
NDValue="#{node.name}"
NDType="java.lang.String"/>
</methodAction>
Do you have any idea of what I'm doind wrong?
Thank you for your help

I finally got this to work by defining the tree model in a managed bean. So there must be something wrong with my iterator binding...
