This discussion is going nowhere.
Adding <li> tag is not browser safe? First, it is not true; second - it's
not the point. Let's say i want to call 'addNewItemToMyList()' function on
the client instead. How should I do this so that my component is *reusable*
in both cases - when I update it from ajax call or using regular page
update. Behavior seems like a good fit, but it is not possible to remove a
behavior from the component, so one time use behaviors are not possible.
Here is how it might work: you have a behavior that generates whatever you
want when component is added to ajaxrequesttarget, sometimes overriding
markup generated by the component. This behavior is added by the component
when you call certain component methods (like itemAdded()) and should remove
itself from the component after request processing is done. This way you can
customize output of ajaxrequesttarget.add(component). Also, at the moment
javascript files (and other resources) are nicely packages, but there are no
mechanism for javascript namespaces (i'd like to see all component-related
javascript to reside in its own private namespace on the client, so there
are no conflicts).
I have a feeling that wicket is not javascript-friendly. AjaxRequestTarget
seems to be taconite limited edition (tm) (see
http://taconite.sourceforge.net/), and it is not clear to me how to create
reusable ajax/javascript widgets using wicket. I hope it is possible, but
not very well documented.

What you typically want to do is to redraw the complete <ul></ul>
part, because most browsers really don't appreciate when you replace
parts of a tag, especially when you are working with a <table>.
"
just adding a line <li> there with JS isnt browsersafe - you can however
still do it if you provide a own ListView implementation.

That solution will replace <ul> element and all of its children, which is
not what I want.
I need something like one-time-use javascript behavior, which can be
attached to a component and then discarded after first rendering.
