The same approach as this can be used with A4J with a4j:support and a4j:region tags to use AJAX to update the zone instead of a full page refresh.

First off, don't use the OptionalValidationFramework. There's always a better solution. Second, I'm still trying to wrap my mind around this problem, so my answer might be flawed. Third, I'm going to use a checkbox since I have made almost no use of radio buttons to date. A quick test of this code works. <t:saveState id="required" value="#{optionalRequired.required}"/> <t:messages globalOnly="true" showDetail="true" /> <t:messages globalOnly="false" showDetail="true" /> <sandbox:subForm id="requiredForm"> <h:selectBooleanCheckbox value="#{optionalRequired.required}"> <sandbox:submitOnEvent for="executeButton" /> </h:selectBooleanCheckbox> <h:commandButton id="executeButton" value="Immediate Submit"/> </sandbox:subForm> <sandbox:subForm id="textForm"> <h:inputText required="#{optionalRequired.required}" value="#{optionalRequired.text}"> </h:inputText> <h:commandButton value="Submit"/> </sandbox:subForm> public class OptionalRequired { private boolean required; private String text; public boolean isRequired() { return required; } public void setRequired(boolean required) { this.required = required; } public String getText() { return text; } public void setText(String value) { this.text = value; } } On 4/15/07, Bjørn T Johansen <[EMAIL PROTECTED]> wrote: > I have small problem and I was wondering how people get around this... > > I have a radiobutton with yes or no as the two choices that decides if a text field should be rendered or not (choosing yes or no > will submit the page)...
