While the JSNI path is (more than) OK when prototyping your port, I'd
recommend you create a widget that suits your needs instead.
You could also (now, or as part of the widget) take advantage of event
bubbling: register a ClickHandler at the container level, look at the
ClickEvent.getNativeEvent().getEventTarget() (it should be an Element,
check with Element.is(...) and cast with Element.as(...)) and walk up
the tree (getParent) until you find a LI (elem.getTagName
().equalsIgnoreCase(LIElement.TAG)) or your widget's element
(getElement()). FYI, that's what the grids (Grid and FlexTable) in GWT
do for the "cell click" events.

I doubt it'll work (I'm almost sure it won't; JSNI reference resolving
is done by parsing the JavaScript code, not using regexes and find/
replace).
