Constraints / limitations of af:message for inline message display ?

Question

Using JDev 11.1.1.3; reading the help content, it seems very simple to drop an af:message component onto the page, and associate with a component for validation message display. Trying it inside a popup belonging to a jspx page works fine, but when I try and use it inside a popup contained within a bounded task flow / fragment, the validation framework appears to be ignoring the message component, and using the balloon hint message display instead. Thinking maybe the For/edit property selection isn't properly handling the nesting of components, I've located the message components closer/next to the source component, but no change ...
<af:panelFormLayout id="pfl2" labelAlignment="top">
<af:panelLabelAndMessage id="pgl3" label="#{bindings.CtFlag.label}">
<af:panelGroupLayout id="pgl5" layout="horizontal">
<af:selectOneRadio value="#{bindings.CtFlag.inputValue}" required="#{bindings.CtFlag.hints.mandatory}"
shortDesc="#{bindings.CtFlag.hints.tooltip}" id="sorct" autoSubmit="true"
layout="horizontal" simple="true"
valueChangeListener="#{backingBeanScope.ClaimMedical.setConditionCtFlag}">
<f:selectItems value="#{bindings.CtFlag.items}" id="si2"/>
</af:selectOneRadio>
<af:spacer width="10" height="3" id="s3b"/>
<af:inputDate value="#{bindings.CtFromDate.inputValue}" label="#{bindings.CtFromDate.hints.label}"
required="#{backingBeanScope.ClaimMedical.ctPeriodRequired}" shortDesc="#{bindings.CtFromDate.hints.tooltip}"
id="idctf" columns="10" partialTriggers="sorct" disabled="#{!backingBeanScope.ClaimMedical.ctPeriodRequired}"> <<<<<<<<<<
<f:validator binding="#{bindings.CtFromDate.validator}"/>
<af:convertDateTime type="date" pattern="#{Constants.dateFormat}"/>
</af:inputDate>
<af:spacer width="5" height="3" id="s3c"/>
<af:inputDate value="#{bindings.CtThruDate.inputValue}" label="#{bindings.CtThruDate.hints.label}"
required="#{backingBeanScope.ClaimMedical.ctPeriodRequired}" shortDesc="#{bindings.CtThruDate.hints.tooltip}"
id="idctt" columns="10" partialTriggers="sorct" disabled="#{!backingBeanScope.ClaimMedical.ctPeriodRequired}"> <<<<<<<<<<
<f:validator binding="#{bindings.CtThruDate.validator}"/>
<af:convertDateTime type="date" pattern="#{Constants.dateFormat}"/>
</af:inputDate>
<af:message id="m3" for="idctf"/> <<<<<<<<<<<<
</af:panelGroupLayout>
</af:panelLabelAndMessage>
</af:panelFormLayout>
<af:message id="m4" for="idctt"/> <<<<<<<<<<<<
Doesn't seem to matter where I put them inside the popup, they don't display. I've used/removed the immediate/auto-submit properties on the inputDate, but no change.
Are there constraints in when/how these can be used, or if not, what is it that I'm missing ?
Thanks,

Hi Srikavi,
to achieve a Validation of an item when leaving the field you'll have to use some javascript code (as ApexLib does internally).
What do you need:
- onChange - Event on your Item
- some Javascript code which is called in the onChange Event (you can put this code either in your page html header or, if it is used more often in your application, in a seperate js File)
- call the ApexLib method apexlib.error.showError to display your error
I actually never tried it myself, but i'm pretty sure that this will work (according to what i've seen in the ApexLib code).
Have fun and tell us how it went,
Peter
