Igor opened SPR-16543 and commented

Is it correct behaviour that org.springframework.web.jsf.el.WebApplicationContextFacesELResolver#isReadOnly
always return false?

The return value is effectively being ignored if the property is not marked as resolved, so the fallback value doesn't really matter... That said, when we resolve the WebApplicationContext there, we should actually return true since a setValue call will never apply to it.
