#
# This method works the same way as the getHtml() method above,
# but as expected, the callback produces JSON instead of HTML, and
# does not call the template engine.
#
# Note that we use our own JSON encoder. This is actually just an
# extension to the JSON encoder provided by the standard library,
# but it has a few nice features that the standard JSON encoder
# doesn't have. For example, it allows each class to define its
# own JSON encoder method, called __json__(), which will be called
# if available to convert an object to JSON.
