Reg SelectOneChoice and SelectManyShuttle combination

Question

Dear Experts,
I have a scenario, where the shuttle component's leading list will be changing according to the value selection of the selectonechoice. And i need to preserve the trailing list values and need to add it to the trailing list once if the user changes the selection of the value in the selectonechoice. That means, whatever the value selected from the selectone choice, the trailing list of the shuttle component should not chnage.
I have followed frank's blog, http://thepeninsulasedge.com/frank_nimphius/2007/07/15/adf-faces-adf-faces-shuttle-with-pre-selected-values-from-a-selectoncechoice/
i didnt get what i have expected..
Please advise me how to achieve this.
Appreciate your solutions.
Regards,
R N V Prasad.

The shuttle's valueChangeListener event fires when you click >  >>  <  << buttons.
You can collect all the values and append to a list (using vector) whenever the trailing list changes.
In the backing bean
private List shuttleValues = null;
generate accessors.
The below code may not fit for your needs, but you have to do similar stuff.
        RequestContext requestContext = RequestContext.getCurrentInstance();
        shuttleValues = (ArrayList)requestContext.getPageFlowScope().get("rhsList"); //gets existing values
        if (shuttleValues == null){
            shuttleValues = new ArrayList();
        }else{
            Vector vec = new Vector();
            DCIteratorBinding iter= getItrtBindings(iteratorName);
            int startIdx = iter.getRangeSize();
            iter.setRangeSize(-1);
            Row[] rows = iter.getAllRowsInRange();
            if(rows != null && rows.length > 0){
               for(int i=0; i<rows.length; i++){
                   Row r = rows;
vec.add(r.getAttribute(loadAttr));
shuttleValues.addAll(vec); //collecting new values
requestContext.getPageFlowScope().put("rhsList", shuttleValues);
Shuttle's value attribute:
value="#{backingBeanScope.backing_MaintainProf.shuttleValues}"
I have added partialTarget at the end of the valueChangeEvent method:
RequestContext.getCurrentInstance().addPartialTarget(selectOrderShuttle3);
