ADF selectOnechoice how to display label in items - oracle-adf

Question

I am working on ADF. I need to display help text on mouse hover for each value of drop down. I struggled al lot but dint find any thing to do in model layer. Finally I endded up playing with string EL expression.
<af:table value="#{bindings.LetterUIConfig1.collectionModel}" rendered="false"
width="98%" styleClass="AFStretchWidth" var="row"
rows="#{bindings.LetterUIConfig1.rangeSize}"
emptyText="#{bindings.LetterUIConfig1.viewable ? 'No data to display.' : 'Access Denied.'}"
fetchSize="#{bindings.LetterUIConfig1.rangeSize}"
rowBandingInterval="0" id="t1" columnStretching="column:c1"
inlineStyle="border-style:hidden;" horizontalGridVisible="false"
verticalGridVisible="false">
<af:column sortProperty="#{bindings.LetterUIConfig1.hints.Name.name}"
sortable="false" id="c1" noWrap="false" headerText="">
<af:panelFormLayout id="pfl1" labelWidth="40%" fieldWidth="60%"
maxColumns="1" labelAlignment="start">
<af:panelLabelAndMessage label="#{row.Name}" id="plam1"
styleClass="alignLeft"
labelStyle="text-align: left;">
<af:panelGroupLayout id="pgl1">
<af:selectOneChoice value="#{row.bindings.Name.inputValue}"
label="#{row.bindings.Name.label}"
required="#{bindings.LetterUIConfig1.hints.Name.mandatory}"
shortDesc="#{bindings.LetterUIConfig1.hints.Name.tooltip}"
id="soc1">
<af:forEach items="#{bindings.LetterAttributeLOV.rangeSet}" var="list">
<af:selectItem id="si1" value="#{list.AttVal}"/>
</af:forEach>
</af:selectOneChoice>
<af:selectBooleanCheckbox value="#{row.bindings.Name.inputValue}"
rendered="#{row.Type eq 'SBC'}"
label="#{row.bindings.Name.label}"
shortDesc="#{bindings.LetterUIConfig1.hints.Name.tooltip}"
id="sbc1"/>
<af:selectManyCheckbox label="#{row.Name}" id="smc1"
rendered="#{row.Type eq 'SMC'}">
<f:selectItems value="#{row.bindings.Name.items}" id="si2"/>
</af:selectManyCheckbox>
</af:panelGroupLayout>
</af:panelLabelAndMessage>
</af:panelFormLayout>
<af:spacer id="s1" height="10"/>
</af:column>
My problem is select item is not displaying substring it is displaying only value. I did use valuePassThrough but no luck.

Try a define method for initialize to itemList;
public List getSelectItemList(){
ArrayList list = new ArrayList();
Iterator<Object> iterator = resolveExpression("#{bind here your LOV}");
while (iterator.hasNext()) {
Object obj= iterator.next();
list.add(new SelectItem(enterObjValue, enterObjValueLabel));
}
return list;
}
public Object resolveExpression(String expression) {
FacesContext fc = getFacesContext();
ELContext elCtx = fc.getELContext();
return fc.getApplication().getExpressionFactory().createValueExpression(elCtx, expression, Object.class).getValue(elCtx);
}
and bind this list to Select one choice component.
<af:selectOneChoice value="#{row.bindings.Name.inputValue}"
label="#{row.bindings.Name.label}"
required="#{bindings.LetterUIConfig1.hints.Name.mandatory}"
shortDesc="#{bindings.LetterUIConfig1.hints.Name.tooltip}"
id="soc1">
<f:selectItems value="#{yourBean.selectItemList}"
id="sadsadsa"/>
</af:selectOneChoice>
