Given the component: https://www.primefaces.org/showcase/ui/input/oneMenu.xhtml
Full source for my test is at: https://github.com/dannymk/PrimefacesTest
Can't get the component to work with an Object using a converter. Not sure how to solve this one.

I get errors like:
java.lang.ClassCastException: java.lang.String cannot be cast to org.primefaces.test.Player
at org.primefaces.test.PlayerConverter.getAsString(PlayerConverter.java:38)
It does not seem to matter what I change and believe me I have tried plenty of implementations of the converter and in the view using "#{palyerConverter}" instead of "playerConverter" and still can't get it to work.
