So, your interest is to pass some values to the next page? Then it is
not necessary to use the inputHidden components. If you want, you can
pass the parameters with the command component and do whatever logic
you need with this parameters in the backing bean:
<h:commandButton value="Send"
actionListener="#{yourBean.doSomethingWithTheParams}" action="rBean">
<f:param name="raId" value="#{var.ra}"/>
<f:param name="rbId" value="#{var.rb}"/>
<f:param name="rcId" value="#{var.rc}"/>
</h:commandButton>
You can also use t:updateActionListener component to implement faster
a master-detail effect. See the example [1] to see how it works.
