Not highlighting error fields in subform when displaying FacesMessages

Question

Hi,
I am trying to display FacesMessage on UI and highlight the errored field. It is working as expected if my fields are NOT in subform like this:
<af:form>
<af:inputText label="Label 159" id="it5"/>
<af:commandButton text="commandButton 2" id="cb3"
action="#{viewScope.backing_testFormLayout.validateRecordset}"/>
</af:form>
java codes:
public String validateRecordset() {
FacesContext fc = FacesContext.getCurrentInstance();
fc.addMessage("it5", new FacesMessage(FacesMessage.SEVERITY_ERROR,
"Parameter Name is required",
null));
return null;
However, if my fields are in subform, the FaceMessage error is displayed, but the errored field ("it5") is not highlighted.
<af:form>
<af:subform id="s9">
<af:inputText label="Label 159" id="it5"/>
<af:commandButton text="commandButton 2" id="cb3"
action="#{viewScope.backing_testFormLayout.validateRecordset}"/>
</af:subform>
</af:form>
Any ideas?
Thanks

Use s1:it5 as the id of the input Text component instead -
public String validateRecordset() {
FacesContext fc = FacesContext.getCurrentInstance();
fc.addMessage("s1:it5", new FacesMessage(FacesMessage.SEVERITY_ERROR,
"Parameter Name is required",
null)); On a sidenote its always better to use bean binding instead of hardcoded id's to avoid issues downstream during maintainance and changes when id changes.
Also add partialSubmit= true to avoid a full page submit.
