These would need to have different id values. I'd recommend just
leaving the id tag off.
But I'm not sure how to handle the output to <t:message>. Is that something
the "validateRequiredIf" custom code would take care of?
No, that's the easy part. A validator throws a ValidatorException()
and part of that exception is a FacesMessage. So the validator would
generate the message while validating.
I'm still not sure that the design is such that all of the "how it
will work" details have been figured out. Actually writing the
validator is easy enough. Cloning the compareToValidator and
changing the condition checked is pretty trivial.

Mike,
Sorry I've got back to you late on this. If you know how to create custom
validators (I haven't delved into that aspect of JSF yet), that would be
great. I can see with your dates how the "ne" operator might be beneficial,
for the radio button/text field, maybe not. This is the way I would set up
my app with the radio button/input fields:
<t:panelGroup>
<t:selectOneRadio id="myRadio" value="#{myBean.myRadio}" >
<f:selectItem itemValue="0" itemLabel="#{text['radio1']}" />
<f:selectItem itemValue="1" itemLabel="#{text['radio2']}" />
</t:selectOneRadio>
<h:panelGrid columns="3">
<t:radio for="myRadio" index="0" />
<validateRequiredIf for="inputText1" >
</t:radio>
<h:inputText id="inputText1" value="#{myBean.inputText1}" />
<t:message id="msgError" for="inputText1" />
<t:radio for="myRadio" index="1" />
<validateRequiredIf for="inputText2" >
</t:radio>
<h:inputText id="inputText2" value="#{myBean.inputText2}" />
<t:message id="msgError" for="inputText2" />
</h:panelGrid>
</t:panelGroup>
But I'm not sure how to handle the output to <t:message>. Is that something
the "validateRequiredIf" custom code would take care of?
Let me know if there's anything I can do. (Read up on custom validation for
one.)
