As a Wicket neophyte myself I can't comment on most of this, but we
did just look deeply into the notion of subclassing components for the
purpose of making them render as rich text widgets from ExtJS.  Having
just done that I will say that there are ALOT of little hidden nits
and difficulties that come up in such an effort.  Wicket and ExtJS
both want to control the rendering of the end markup, so when you
replace the generated markup with Ext widgets, many of Wicket's little
pre-created solutions for various internet use cases breaks.  Each
problem is circumventable, but eventually you find yourself almost
writing your own framework rather than extending a framework.

I would really love it if a more experienced Wicket developer took a
serious crack at creating a Wicket extension that worked with rich
internet controls.  I get the feeling that my effort failed as much
because I didn't have deep Wicket knowledge as anything else.
