JDEV 10.1.3 How to manipulate/Debug IndirectList from ejb 3.0 session bean

Question

I was debugging my session bean a seen that element data for the employeesCollection was empty.
I didn't understood why my java client was throwing an error when i accessed manually the Departments collection and get the employeeCollection from the first entry in the collection. What was confusing me was that my master/detail jfs application was displaying these data. From where ? how was it possible ? it was the same session bean !
This is the reason i debugged the session bean return object and seen that the collection was also empty as the from executing from my java client application. I have seen the type of the object that was not a collection but IndirectList.
So my question ! how is it possible to load the collection of this type ? Which method the data control is executing to load it ? Where may i found a description of this very interesting process ?

Hi Frank.
plain English - on plan :).
I create managed bean with function which do access to LDAP and this function 'return List<Users>'.
In JDeveloper :) on managed bean(java class) i create "Create Data Control"... after, from Data Controls i drop on page this data(create ADF Table with selectOne)...
First Page Ready!
Second page... i need to know which option selected on first page. This option(row) contains, UserName and etc... On second page i again fetch data, from LDAP, associated with this concrete UserName... Because i fetch data using managed bean :) i need to know this username in my managed bean...
May be :) im wrong...
sessionAttribute - like this? ->
* Convenience method for setting Session variables
* @param ctx FacesContext
* @param key object key
* @param object value to store
public static void storeOnSession(FacesContext ctx, String key, Object object) {
Map sessionState = ctx.getExternalContext().getSessionMap();
sessionState.put(key, object);
* Convenience method for getting Session variables
* @param ctx FacesContext
* @param key object key
public static Object getFromSession(FacesContext ctx, String key) {
Map sessionState = ctx.getExternalContext().getSessionMap();
return sessionState.get(key);
}
