Iterating around lists of lists within ADF page - ADF 11g 11.1.1.6

Question

Hi,
I am facing a challenge with a bean backed data control and rendering its contents onto a JSPX page.
The data control looks like this:
http://i48.tinypic.com/2zf1pfl.png
I need to iterate around audioServiceList and within that, seperately iterate around primaryComponents and secondaryServiceComponents.
I have an initial binding to audioServicesList:
+<af:iterator value="#{bindings.audioServiceList.collectionModel}" var="audioService" id="a1">+
but don't fully understand how I get a specific child of the variable audioService.
I need to get a handle onto both the children, individually, to iterate around that collection
Is it a case of accessing it via #{audioService.primaryComponents}
+<af:iterator value="#{audioService.primaryComponents.collectionModel}" var="audioService" id="a1">+
I understand there is the .children notation but I dont think I can choose which child I get returned (as there are some attributes underneath audioServiceList and then 2 lists)
Any help would be appreciated.
Regards
Jason

Answer 1

OK,
I am unsure how to get the underlying list to pass it to an iterator. If I were to use a seperate iterator underneath, how do I get access to the underlying list in the first place to pass it to an iterator?
I am thinking of something like this but I know it is wrong:
+<af:iterator value="#{audioServiceList.primaryComponents.collectionModel}" var="audioService" id="a1">+
+...+
+<af:iterator value="#{audioService.children[3]}" var="primaryComponentList" id="a2">+
or
+<af:iterator value="#{audioService.primaryComponent}" var="primaryComponentList" id="a2">+
