Depends exactly what you're trying to accomplish. For the case you're
describing (ajaxly swaping a widget) what I usually do is what you're
doing: placing the widget in a container and then calling a
controller method that returns a rendered widget to swap the contents
of the container with innerHTML.
However, if I just need the DOM id of the widget to initialize some
JS structure (like TinyMCE or SelectShuttle) does, I usually use the
"field_id" template variable to refer to it (instead of refering to
the container and looking for it's first child). However, as I've
mentioned many times already, one "limitation" (at least for my
liking) of widgets is that you can only access this variable inside
update_params or inside the template, which makes hard (IMO) to pass
this info around to "connect" different widgets.
