Major Description
Please allow AjaxLink to provide an empty getChannelName() that is called by its internal AjaxEventBehavior, so that Ajax-Channels can be used without
overriding the whole behavior.
I know, not all methods should be provided and I also know its possible to override the AjaxEventBehavior, but an AjaxLink should at least provide the Possibility
to assign it to a specific Channel.
THanks..
