To have the relevant value

Question

Hi,
In the jsf, we can choose a value from the LOV like
<af:selectOneChoice value="#{bindings.Categor.inputValue}"
label="Category"
required="#{bindings.Categor.hints.mandatory}"
shortDesc="#{bindings.Categor.hints.tooltip}"
id="soc1">
<f:selectItems value="#{bindings.Categor.items}"
id="si2"/>
</af:selectOneChoice>
for the sql of the LOV, we have another column like "id" for each Categor value. How to hold the value of "id" in the jsf, when one Categor value has been chosen?

shortDesc="#{bindings.Categor.hints.tooltip}"
id="soc1">
<f:selectItems value="#{bindings.Categor.items}"
id="si2"/>
</af:selectOneChoice>
<af:spacer width="125" height="10" id="s3"/>
<af:panelLabelAndMessage label="ID" id="plam1">
<af:outputText id="ot1"
value="#{bindings.Id.attributeValue}"
partialTriggers="soc1"></af:outputText>
</af:panelLabelAndMessage>but ot1 is not refreshed when I change the selection
