Best way to implement selectOneRadio component with "other" option

Question

I have a selectOneRadio component that has an other option (see below). If the other option is selected I need to pull the value out of a text field. Any ideas on the best way (or any way) to
implement this?
This is how it looks on the screen...
Please select one...
o 10.00
o 20.00
o 30.00
o Other amount [    ] <--- Text box
When I try to access the value of the selectOneRadio component in the backing bean I get the index of the selection instead of the item value that was selected.
This is in 11g.
Any help would be appreciated.
Thanks,
Mike

Hi Mike,
I came up with the following codes as I assume you populate the selectOneRadio from a VO. The inputText will only be rendered if the "Others" option is selected. And you can get the actual ID of the selected items instead of their index.
/** Jspx **/
<af:panelFormLayout partialTriggers="rdbPrice">
  <f:facet name="footer"/>
  <af:selectOneRadio value="#{bindings.SampleVO1.inputValue}"
                     label="#{bindings.SampleVO1.label}"
                     required="#{bindings.SampleVO1.hints.mandatory}"
                     shortDesc="#{bindings.SampleVO1.hints.tooltip}"
                     id="rdbPrice" autoSubmit="true">
    <f:selectItems value="#{bindings.SampleVO1.items}"/>
  </af:selectOneRadio>
  <af:panelLabelAndMessage label="Label 1"
                           rendered="#{bindings.priceId.inputValue == 98}">
    <af:inputText label="Label 1"
                  binding="#{backingbean.txtOthers}"
                  simple="true"/>
  </af:panelLabelAndMessage>
</af:panelFormLayout>
/** PageDef **/
<bindings>
  <list ...>
  </list>
  <attributeValues IterBinding="SampleVO1Iterator" id="priceId">
    <AttrNames>
      <Item Value="priceId"/>
    </AttrNames>
  </attributeValues>
</bindings>
/** backing bean **/
public void yourMethod() {
    String priceId = getBeanValue("#{bindings.priceId.inputValue}").toString();
    System.out.println(priceId);
}Note:
1) It is assumed that the value 98 refers to the "Others" ID value.
2) The priceId attribute type in the SampleVO has to be changed to Long (my default was Number).
3) The getBeanValue() is the usual getValue call of a ValueBinding or ValueExpression.
