Comment 2 Peter Zavadsky 2008-11-14 22:45:58 UTC 
There seems to be an issue with the com.sun.faces.application.Application.getConverterTypes() method. The implementation
(it was probably com.sun.faces.application.ApplicationImpl) should return an iterator over classes, but there seems to
be also string included.

I am adding generics to the client code, to better detect the problem if it appears again. However I am not sure which
implementation got there, and how did it pass non class object into it (probably a non-generic implementation).

Please, reopen with the new information if it happens again.

Fixed:
