@validator('formBeanValidator'... does not validate nested properties

the JSR-303 formBeanValidator does not iterate through nested form fields even if they are annotated with the @Valid annotation and have a Constraint on the nested property

e.g.

<intbox value="@bind(fx.age)" errorMessage="@load(vmsgs['p_age'])"/>  <!-- works -->
<textbox value="@bind(fx.nameDto.name)" errorMessage="@load(vmsgs['p_nameDto.name'])"/>  <!-- does not work / not even sure about the syntax of 'p_????' -->

the attached example is a running maven project showing this behaviour
