URGENT: How to build composite custom component with a valuechangelistener?

Question

Hi there!
I already posted regarding this issue before but unfortunately there wasn't any answer. But I don't think what I am trying to achieve is something unusual.
I am trying to build a composite custom component, that consists of some UISelectOne components and some UIInputText fields. Now I need to fill the combo boxes depending on the selected values of the other boxes. Therefore I added a value change listener. But when it fires I get an index out of bounds exception on the page.
The problem seems to be that the child components are being added twice to the component: Once in the constructor (which I am doing and which is called everytime the component is built) and once as part of the Restore View Phase (which JSF is doing).
So my question is: How and where do I correctly initialize my component's children?
A full code example can be found under http://forum.java.sun.com/thread.jspa?threadID=586301&tstart=150
Thanks a lot in advance!

#2 sounds utterly strange to me. How would I utilize the phase id?The code below shows my idea whereas I never validate it in any real projects:
public class MyPhaseListener implements PhaseListener {
     private static final String IDKEY = "PHASEID";
     public static PhaseId getCurrentPhaseId() {
          return (PhaseId) FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get(IDKEY);
     public void beforePhase(PhaseEvent event) {
event.getFacesContext().getExternalContext().getRequestMap().put(IDKEY,event.getPhaseId());
     public PhaseId getPhaseId() {
          return PhaseId.ANY_PHASE;
}You can write your constructor like as:
if (MyPhaseListener.getCurrentPhaseId().equals(PhaseId.RENDER_RESPONSE ) {
     /* create children because this is the first time to create the component */
}
