Good evening, I have the following context: My application uses JSF2, CDI and Primefaces, my view is yielding normally, however, if I start an F5 repeatedly ends up returning me the error of Rendering View with Nullpointerexception, my view is annotated with @Viewscoped if I switch to @Request the problem ends.
