Question about encoding/decoding a custom UIComponent

Question

Hello,
I am trying to create a custom JSF component using the following code :
class UICustomCTP extends UIInput {
      * Component that holds a list of Norms
     public static final String COMPONENT_TYPE = "org.alfresco.faces.CustomCTPInput";
     public static final String COMPONENT_FAMILY = "javax.faces.UIInput";
     // ID's
     private static final String ID_CTPKEY_FLD = "-ctpkey-field";
     private static final String ID_CTPDESC_LST = "-ctpdesc-list";
     @Override
     public String getFamily() {
          return COMPONENT_FAMILY;
     @Override
     public void encodeBegin(FacesContext context) throws IOException {
          // Set-up the dynamic id's
          String idClient = getClientId(context);
          String idCtpKey = idClient + ID_CTPKEY_FLD;
          String idCtpDescList = idClient + ID_CTPDESC_LST;
          ResponseWriter writer = context.getResponseWriter();
          writer.startElement("div", this);
          writer.writeAttribute("id", "ctp-container-part", null);
          writer.writeAttribute("class", "ctp-container-part-style", null);
          writer.write("R�sum� :");
          writer.startElement("input", this);
          writer.writeAttribute("id", idCtpKey, idCtpKey); // is the property name should be the same as the key?
          writer.writeAttribute("type", "text", null);
          writer.writeAttribute("value", "", null);
          writer.writeAttribute("style", "width:20px", null);
          writer.endElement("input");
          writer.startElement("select", this);
          writer.writeAttribute("id", idCtpDescList, idCtpDescList); // is the property name should be the same as the key?
          writer.writeAttribute("size", "5", null);
          writer.writeAttribute("style", "width:300px", null);
          writer.writeAttribute("multiple", "1", null);     
               there's many option items here
          writer.endElement("select");
          writer.endElement("div");
          super.encodeBegin(context);
     @Override
     public void decode(FacesContext context) {
          super.decode(context);
          // Set-up the dynamic id's
          String idClient = getClientId(context);
          String idCtpKey = idClient + ID_CTPKEY_FLD;
          String idCtpDescList = idClient + ID_CTPDESC_LST;
          // retrieve the request
          Map requestParamMap = context.getExternalContext().getRequestParameterMap();
          String ctpKeyInputValue = (String) requestParamMap.get(idCtpKey);
          List<String> ctpDescInputValueList = (List<String>) requestParamMap.get(idCtpDescList);
          Object ctp = new CTPItem(ctpKeyInputValue, ctpDescInputValueList);
          setSubmittedValue(ctp);
          setValid(true);
     @Override
     protected Object getConvertedValue(FacesContext context, Object submittedValue) {
          CTPItem ctpItem = (CTPItem)submittedValue;
          return ctpItem;
     } I don't have, and don't need and I cannot use renderer, tag definition, taglib definition because this component is generated through Alfresco ECM
(and I don't have access to the JSP (not authorised)).
My problem:
When I try to read the inputs through request parameters :
      String ctpKeyInputValue = (String) requestParamMap.get(idCtpKey);
      List<String> ctpDescInputValueList = (List<String>) requestParamMap.get(idCtpDescList);It returns always null.
It's is not very clear what value to put in the third parameters in writeAttribute and what is the logic behind with that property.
It looks like I forget to implements something but cannot find what. I read many tutorials and forums but didn t find any solution.
Thanks if somebody can help me.

Silly me... just forget that id and name are not the same...
Thanks, it work perfectly with name attributes.
