The point is that my property is named 'text', and i have also a resource bundle called 'text'. Additionally in the javax.el.CompositeELResolver the org.apache.myfaces.el.unified.resolver.ResourceBundleResolver is before the javax.el.BeanELResolver.
And the org.apache.myfaces.el.unified.resolver.ResourceBundleResolver.setValue(ELContext context, Object base, Object property, Object value) method does NOT check the base object and just looks for a resource bundle named as the property, in my case it finds something and peng! Exception!
It should check (base != null) and just leave.
