Subject Re: How to create JSF pages on the fly?
Date Thu, 29 Dec 2005 00:53:57 GMT
Yeah you are right if your page is totally dynamic wich is rarely the
case in my mind. Using your approach, the backing bean would have to
reattach everything to the last children added wich is rather ugly and
complex. You can insert the clay component anywhere in your page and
just don't care about the rest of it (hence it allows you to define a
subview at runtime). But depends of your needs I guess.
