Issue with h:selectManyListBox - java.util.NoSuchElementException

Question

I facing an issue with <h:selectManyListBoxs in JSF 1.1 with portlets.
I am using RAD 7.5.3 and server is Web sphere Portal v6.1 Server on WAS 7.
I have two <h:selectManyListbox moving options from Left to Right which i am doing in Javascript and it is perectly working fine.
For the right hand side list box i have an additional movement for up and down which i am doing in javascript and it is working fine.
Now the issue when I move from left to right and click on Save it is working fine. when I try to touch/select the options
in right hand side list box and click on save i am getting NoSuchElementException in the processValidation phase as shown below.
(It is not calling the save function at all in this case, it just calling the getLinkedBenchmarks method and failing).
I added the attribute as immediate= true and the exception is comming now in APPLY_REQUEST phase.
JSF1054: (Phase ID: PROCESS_VALIDATIONS 3, View ID: /jsp/Test.jsp) Exception thrown during phase execution:

public Map<String, Index> getAvailableBenchmarks() {

          System.out.println("Linked Bench marks in getAvailableBM.. " + linkedBM);

Additional info:
     I override the equals and hashcode method in the Object class as suggested on the internet.
     I added the Custom converter by implementing javax.faces.convert.Converter and
     @Override
     public String getAsString(FacesContext arg0, UIComponent arg1, Object obj) {
          if(obj == null){
               return null;
          } else if(obj instanceof Index){
               final TAPIndex index = (Index) obj;
               return index.getIndexName().toString();
          } else if(obj instanceof Objective){     
               final InvestmentObjective invest = (Objective) obj;
               return invest.getDescription()+" (" + invest.getCode() + ")".toString();
          return obj.toString();
     @Override
     public Object getAsObject(FacesContext arg0, UIComponent arg1, String value) {
               return value;
I have no Idea why it is behaving like this. Please help me.Edited by: Joglekar on Sep 17, 2010 10:17 AM

Answer 1

Here is the proof - Let me know if am doing any thing wrong! FYI, I used JSF portlets in RAD 7.5.3 and Websphere portal server v6.1.
I have two SelectManyListBox components and moving the options from left to right using Javascript and then select one of the options in the right hand side list box and click on submit. You will see the NosuchElementException.
I don't have any logic inside my bean class in any of the methods.
