Custom data control createRowData(DCRowContext ctx)

Question

Custom data control createRowData(DCRowContext ctx)
public Object createRowData(DCRowContext ctx) {
System.out.println("createRowData()");
DCRowSetIteratorImpl rsi = (DCRowSetIteratorImpl)ctx.getRowSetIterator();
ARow row = new ARow(new PersonTO(new Integer(122),"Juhan", "Santiago", "223311" ), rsi);
return row;
I overrode this method in my custom data control class ( MyCustomDataControl extends EjbDataControl)
However the returned row is not added to the rowsetiterator. ARow is a custom class which extends RowImpl,
there i only overrode the constructor. PersonTO is what would be returned by ctx.getRowDataProvider().
How can i get a PersonTO to be inserted into the rowsetiterator to which the ctx refers?
Many thanks!

I know... But at the moment it's the only solution i can see that works.
I have tested it by executing the EL in my data control to retreive the value from my TF input parameter and it works.
So basically i am trying to write a DC that will retreive information from another system. As an input parameter of the taskflow, you need to specify the name of that system and it's that parameter I want to pass to my DC. So currently I have something like this:
    public MyDC() {
        super();
        System.out.println("calling constructor");
        String system = (String)get("#{pageFlowScope.system}");
        System.out.println("System: " + system);
        SessionFactory factory = new SessionFactory(system);
        Session session = factory.getCurrentSession();
        System.out.println("init complete");
    }SessionFactory and Session are from the custom java API so don't bother about that :)
I have tested this and it works but I know it's not the best solution... (that's why I wrote this post)
Based upon that, is there a better way for passing the system name to the DC?
