Dependent Selectonechoice boxes error

Question

Hi All,
I am using jdeveloper 11g.
I have two dependent dropdown boxes (Category and services).
Everytime i change the category, the services dropdown needs to be refreshed.
I am not using any view objects.
The dropdowns are working fine (that is when i change the category, services do get refreshed), but lets say i select a category "A"
and then select a service "serviceA" then go back to category and change that to "B", it refreshes the services dropdown
but adds an empty row above "select service" option.
and logs show the following error
<SimpleSelectOneRenderer><_getSelectedIndex> Could not find selected item matching value "2,Satisfaction Survey"
in RichSelectOneChoice[UIXEditableFacesBeanImpl, id=soc4]Following is the code for the dropdown menus
<af:selectOneChoice label="Report Category"
            binding="#{backing_RequestForm.soc3}"
             id="soc3" valueChangeListener="#{backing_RequestForm.loadServiceList}"
autoSubmit="true" required="true" immediate="true">
            <f:selectItems value="#{backing_RequestForm.reportCategoryList}"
                            id="si26"/>
          </af:selectOneChoice>
            <af:selectOneChoice label="Service"
                              binding="#{backing_RequestForm.soc4}"
                              id="soc4" partialTriggers="soc3" autoSubmit="true"
required="true" immediate="true">
            <f:selectItems value="#{backing_RequestForm.serviceListFinal}"
                            id="si27"/>
          </af:selectOneChoice>i tried the above code removing immediate, requried attributes, yet in the logs i get the same error.
Any idea on what i could be missing ??
Thanks

Hi,
What difficulty are you facing exactly.
Is your depended dropdown fetching values correctly??
My problem was that when i select a value in dropdown A and a value is dropdown B, then go back and change the value of A, the values in B got refreshed but added an extra blank entry in the dropdown and also in the logs shows the following error
SimpleSelectOneRenderer><_getSelectedIndex> Could not find selected item matching value "2,Satisfaction Survey" in RichSelectOneChoice[UIXEditableFacesBeanImp
Is this the problem you are facing??
If so, in valuechangelisterner method, i added the code for the resetting the selectonechoicebox.
    if(event.getNewValue().equals("") || event.getNewValue() == "" || event.getNewValue() == null || event.getNewValue().equals(null) ){
   // reset the drop down to avoid <SimpleSelectOneRenderer><_getSelectedIndex> Could not find selected  error  
// soc3 and soc4 are the ids of selectonechoice component
      soc3.resetValue();
      soc4.resetValue();
      serviceListFinal = new ArrayList<SelectItem>();
     this.serviceListFinal.add(new SelectItem("","Select service"));
else{
soc4.resetValue();
  String catDesc = event.getNewValue().toString();
  // code for populating the dependent dropdown
   }Hope this helps
