well, I could try with javascript on the client but that is something I wanted to avoid.

Any recommendation?

RichFaces or Ajax4jsf does not have a solution there, do they?
Do I have to configure MyFaces too?
or there is another framework which is easy to install and not invasive?

Thanks for any thoughts!

very good!
