Custom component help

Question

Hi,
Could you point me to some documentation/tutorials/examples how to bind to and iterate collection data in the same way as dataTables does?
Well, something a little more easily digested than the RI code for dataTable ;-)
I would like to process a nested iterated tag sort of like
<x:document list="#{thelist}" var="item">
   <x:column>
      <x:data itemdata="#{item.something}"/>
   </x:column>
</x:document>So that I could iterate over the collection and access the "something" attributes
Help much appreciated!
Thanks in advance,
Nik

somethere you will do something like:
FacesContext context = .... ;
List<?> list = component.getList(); //getList asks the ValueExpression of Parameter "list"
for(Object o : list) {
     context.getExternalContext().getRequestMap().put(getItemName(), o); //getItemName() returns the content of parameter "var"
        encodeChildren(...); //or something like that.
context.getExternalContext().getRequestMap().remove(getItemName());The above sample is very short and easy, but you should understand howto set such a temporary el-variable. Pay attention that you need to iterate in every phase (method processValidations, processUpdates, etc.)
