How to make a jsf parameter form with a selectOneChoice and data control

Question

I want to make a parameter form with a selectOneChoice and store this value in a backing bean, so I can use as a bind variable in query. I already made it happen without data control
Can someone show how to do it in adf data control. With the wizard it tries put the value
in a viewobject but I don't have base or destination viewobject. I can change the pagedef
so it works to fill the selectOneChoice but then I want to store the selected value in a session beab
here is solution with the application module and request / session bean, I don't
think it is the right solution
thanks edwin
jsf page
<af:selectOneChoice label="Desk" value="#{selectDesk.desk}"
id="DeskID"
binding="#{selectDesk.deskBinding}"
autoSubmit="true"
valueChangeListener="#{selectDesk.deskChangeListener}">
<f:selectItems value="#{selectDesk.deskSelectItems}"/>
</af:selectOneChoice>
Selektdesk backing bean
public SelectDesk(){
FacesContext facesContext = FacesContext.getCurrentInstance();
ValueBinding valueBinding = facesContext.getApplication().createValueBinding("#{userInfo}");
userInfo = (UserInfo) valueBinding.getValue(facesContext);
public List<SelectItem> getDeskSelectItems() {
if ( userInfo.getSelectItems() != null ) {
selectItems = userInfo.getSelectItems();
return selectItems;
if ( getBindings() != null ) {
userInfo.setBindings( getBindings());
else {
setBindings(userInfo.getBindings()) ;
if ( selectItems == null ) {
selectItems = new ArrayList<SelectItem>();
DCBindingContainer bc = getBindings();
SicmaService sicma = (SicmaService)bc.findDataControl("SicmaServiceDataControl").getDataProvider();
ViewObject desk = sicma.findViewObject("DeskSelectView1");
desk.executeQuery();
RowSet rows = desk.getRowSet();
while (rows.hasNext()) {
Row a = rows.next();
String DskId = a.getAttribute(0).toString();
String DskOms = a.getAttribute(1).toString();
selectItems.add( new SelectItem(DskId ,DskOms ));
rows.closeRowSet();
userInfo.setSelectItems(selectItems);
return selectItems;

The SRDemo has an example of a selectOneRadio bound to a parameter being used to pass to an ExecuteWithParams action (to automatically feed a view object's named bind variable. This is in the SRStaffSearch.jspx page.
Also, if you check out example # 72 from my blog:
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html#72
There is another example of using a selectOneListbox to do the same type of thing.
The steps involved in creating something like this are to:
(1) Define your named bind variables on your view object
(2) Drop the "ExecuteWithParams" action in the operations folder of that view object from the Data Control Palette to your page as a "Parameter Form"
(3) Drop the specific attribute (nested child of the "ExecuteWithParams" action from step (2) as whatever kind of selectOneXXXX control you want
(4) Delete the extra field on the form you don't want.
