Here we go!
<h:outputText value="#{Message.hardware_type}" />
<h:selectOneRadio value="#{ServiceBean.hardwareType}" immediate="true" valueChangeListener="#{ServiceBean.hardwareTypeChanged}">
<f:selectItems value="#{ServiceBean.HWTypes}"/>
</h:selectOneRadio>
public void hardwareTypeChanged(ValueChangeEvent event) throws SQLException, Exception{
FacesContext context = FacesContext.getCurrentInstance();
String prevCategorySelected = (String)event.getOldValue();
String newCategorySelected = (String)event.getNewValue();
if(!newCategorySelected.equalsIgnoreCase(prevCategorySelected)){
// Value changed. Change the drop down values.
if(newCategorySelected.equals("Desktop")){
desktopSelected = true;
debug("Setting desktopSelected field to: "+isDesktopSelected());
}
else if(newCategorySelected.equals("Laptop")){

}
context.renderResponse();
}
}
}
Based on what hardware type is selected Desktop items/laptop items are displayed.
The code for that is
<h:outputText value="#{Message.desktop_type}" rendered="#{ServiceBean.desktopSelected}"/>
<h:panelGroup rendered="#{ServiceBean.desktopSelected}">
<h:selectOneRadio value="#{ServiceBean.desktopType}" id="desktop_type">
<f:selectItem itemValue="Standard User Desktop" itemLabel="Standard User Desktop" />
<f:selectItem itemValue="Non User Desktop" itemLabel="Non User Desktop" />
</h:selectOneRadio>
<h:message styleClass="error" for=""/>
</h:panelGroup>
<h:outputText value="#{Message.laptop_type}" rendered="#{ServiceBean.laptopSelected}"/>
<h:panelGroup rendered="#{ServiceBean.laptopSelected}">
<h:selectOneRadio value="#{ServiceBean.laptopType}" id="laptop_type">
<f:selectItem itemValue="Standard User Laptop" itemLabel="Standard User Laptop" />
<f:selectItem itemValue="Power User Laptop" itemLabel="Power User Laptop" />
</h:selectOneRadio>
<h:message styleClass="error" for=""/>
</h:panelGroup>
<h:outputText value="#{Message.docking_station}" rendered="#{ServiceBean.laptopSelected}"/>
<h:panelGroup rendered="#{ServiceBean.laptopSelected}">
<h:selectOneRadio value="#{ServiceBean.dockingStation}" id="docking_station">
<f:selectItem itemValue="Yes" itemLabel="Yes" />
<f:selectItem itemValue="No" itemLabel="No" />
</h:selectOneRadio>
<h:message styleClass="error" for=""/>
</h:panelGroup>
<h:outputText value="#{Message.wireless_access}" rendered="#{ServiceBean.laptopSelected}"/>
<h:panelGroup rendered="#{ServiceBean.laptopSelected}">
<h:selectOneRadio value="#{ServiceBean.wirelessAccess}" id="wireless_access">
<f:selectItem itemValue="Yes" itemLabel="Yes" />
<f:selectItem itemValue="No" itemLabel="No" />
</h:selectOneRadio>
<h:message styleClass="error" for=""/>
</h:panelGroup>
