Currently, if you want to retrieve a jQuery object from a JSF id, you need to write something like :
$('##{rich:clientId('your-id')}')
And that's no even true because the moment you have nested components, there will probably have ":" separators, but that's a selector caracter in jQuery selectors, so it doesn't work.
It would be great to have a shorcut like :
#{rich:jquery('your-id']}
which is more clear and take care of ":" caracters.
