TreeTable with two accessors nodeDefinition

Question

Hello to all!
In my pageDef i have next tree binding:
<tree IterBinding="groupsIterator" id="groupsTreeTable" ChangeEventPolicy="none">
<nodeDefinition DefName="projects.GroupsType" Name="nodeGroups">
<AttrNames>
<Item Value="groupLabel"/>
<Item Value="groupId"/>
</AttrNames>
<Accessors>
<Item Value="themes"/>
</Accessors>
</nodeDefinition>
<nodeDefinition DefName="projects.ThemeType" Name="nodeThemes">
<AttrNames>
<Item Value="themeId"/>
<Item Value="genereteInKML"/>
</AttrNames>
*<Accessors>*
*<Item Value="themeInfo" label="themeInfos">*
*<Item Value="themeKML" label="themeKMLs">*
*</Accessors>*
</nodeDefinition>
<nodeDefinition DefName="projects.ThemeInfoDataType" Name="nodeThemeInfos" >
<AttrNames>
<Item Value="label"/>
<Item Value="column"/>
<Item Value="columnType"/>
<Item Value="id"/>
</AttrNames>
</nodeDefinition>
<nodeDefinition DefName="projects.ThemeKMLType" Name="nodeThemeKMLs">
<AttrNames>
<Item Value="extrude"/>
<Item Value="altitudeMode"/>
<Item Value="color"/>
<Item Value="colorMode"/>
<Item Value="lineStyleWidth"/>
<Item Value="styleId"/>
<Item Value="tessellate"/>
</AttrNames>
</nodeDefinition>
</tree>
Using that binding i builded treetable. It looks like:
->group
-->theme
--->themeInfos
----->themeinfo
--->themeKMLs
----->themeKML
And now is what i need to know is what type of node is selected.
In past i done it using that:
RichTreeTable rTT = (RichTreeTable)getTreeTable();
RowKeySet rks = rTT.getSelectedRowKeys();
Iterator rksIterator = rks.iterator();
CollectionModel model = (CollectionModel)rTT.getValue();
JUCtrlHierBinding rttBinding = (JUCtrlHierBinding)model.getWrappedData();
//if there are nodes in tree table
if (rksIterator.hasNext()) {
while (rksIterator.hasNext()) {
List nodeKey = (List)rksIterator.next();
JUCtrlHierNodeBinding node = rttBinding.findNodeByKeyPath(nodeKey);
node.getHierTypeBinding().getStructureDefName()
But in that time i have no nodes with two or more accessors. treeTable were looking like that:
->group
-->theme
--->themeinfo
In that case I was able to get current node type and, if i need it, add node with same type or add child node to it using previous code.
Now i have this two extra nodes in treeTable (*->themeInfos, ->themeKMLs*) and when i try to get its type, to choose what to do next, i get them parent node type theme.
Is there solution to get exactly "type" of selected node?
P.S. English not my native language, so, excuse me

Hi,
found a solution in Duncan Mills "Oracle JDeveloper 11g Handbook". However, it doesn't allow for two root nodes but sibling child nodes. So not quite what you wanted
