autoSubmit not working when the "blank" option is selected in tr:selectOneChoice

I believe this is the default or expected behavior.
<code>
<tr:selectOneChoice id="country" value="#{actionHandler.country}" label="Country"
        autoSubmit="true" immediate="true" 
        validator="#{actionHandler.validateCountry}">
        <f:selectItems value="#{actionHandler.countryOptions}"/>
</tr:selectOneChoice> 
</code>
In the dropdown, the first option is a blank option. When I select this option, the validator method "validateCountry" is not getting called. 
I would like to change its behavior so that even when I select the blank option, the autoSubmit still submits the value (even if it submits NULL or an empty String -- I don't care). Is there a way to do this?
Many thanks!

On construction of countryOptions add a "new SelectItem(null, "")" and set
country to "" by default. Then the blank is actually bound to a SelectItem
and valueChange will fire.
