    Hi John,

    not sure if it is the error but maybe try adding the public modifier to your class. Besides that, the only thing I can think of is some mismatch of the alias used for tree alias, tree title or section alias.

    Rest looks ok for me.

    Regards David

    Eureka, it was the public modifier. Thanks David.
