Filter the list of inputComboboxListOfValues inside an iterator.

Question

Hello,
I have a worker that has multiple services. I iterate over all services to display them in the worker form. Each service can be modified. A worker can't have the same service twice. I have added in the database unique constrain <worker, service>.
When I add the same service to the worker twice and press save button. No error message shows up.
What I am trying to do is to filter the list of the af:inputComboboxListOfValues to not have an option to select twice the same service of a worker.
Or to display an error message on the component with the service that is appearing twice.
I already tried to filter the inputComboBoxListOfValues list but since it is the same component being iterated can't make the filter work.
[code]
<af:iterator id="iter" var="row" value="#{bindings.WorkerServiceView1.collectionModel}">
     <af:panelGroupLayout id="pgl4" layout="horizontal"  inlineStyle="margin-top:1px">
          <af:inputComboboxListOfValues id="pathShortFullId" value="#{row.bindings.PathShortFull.inputValue}"
                             model="#{row.bindings.PathShortFull.listOfValuesModel}"
                             binding="#{backingBeanScope.wServBacking.inputComboLovService}">
           </af:inputComboboxListOfValues>
     </af:panelGroupLayout>
</af:iterator>
[/code]

I tried recreating the RowClass but didn't help.
Here is how my a little shorter version of my Entity looks like:
