Answer 1

The "<h:command_button..../>" tag generates code that
is something like this:For starters, upgrade to the final release (which calls this tag commandButton, no underscore). 've no idea why anyone is still asking questions about prerelease versions!!
<input type=submit name=_id0:_id7 value="...(Save)"
onclick="document.forms['_id0']['_id0:BEName'].value='Q
otation';
document.forms['_id0']['_id0:BEName'].value='Save';
document.forms['_id0'].submit()">No, it doesn't, not in any recent version. commandLink still uses Javascript, though.
What this means is:
If i disable JavaScript usage in my browser settings
(I tested in MS IE), the above code would not work.
In considerable number of B2C web applications, Java
Script is not used because of lack of control
over Client environment (browser)Is this true? Surveys I have seen suggest that an utterly overwhelming majority of consumers have Javascript turned on.
My Question:
Does Reference Impl. of JSF (Sun) assume that Java
Script would be enabled?Yes, for the renderers delivered in the spec.
In more general terms: is it assumed that JSF-based
HTML UI requires Java Script to be enabled?No, just for the default HTML renderkit, and just for a few (currently, one) renderers in that render kit.
Can the spec team (or someone else) throw light on the
background for this technical implementation, if any?As I said, the overwhelming majority of browsers have Javascript turned on. Some components (commandLink, in particular) could not be implemented without Javascript.
