EL evaluation in non-rendered JSF elements

Is EL #{myBean.property} evaluated in example below? If yes, that means all ELs on page are evaluated regardless of value of their 'rendered' (or any other) attribute?

<h:panelGroup rendered="false">
     <h:outputText value="#{myBean.property}" />
</h:panelGroup>

No. You could also easily answer it yourself by putting a debug breakpoint on the getter method.

That basically depends on how well designed the component is. The standard JSF components doesn't do that, but if it's for example a custom component which doesn't check isRendered() inside processXxx methods before continuing processing itself and children, then all the EL of the children may be evaluated.
