Hi,
The NullPointerException is raised in the following line:
if (!type.equals(String.class) && ! type.equals(Object.class))
Thus type is null.
type is the result of calling getPropertyBinding().getType(facesContext),
which returns null in your case.
However, I don't know exactly why this returns null, but maybe this
clarification is the trigger for someone else, who knows it.
Regards,
Jakob Korherr
