Re: performance Problem with ajax and facelets

????   Are you just guessing have you actually tried it?

Facelets isn't the perf issue here, building the component
tree is cheap-- most of the performance issues come from
actually evaluating the component tree (rendering) which
isn't a responsibility of Facelets, but of the components
themselves.  The 'rendered' attribute is allowed on
ui:fragment, and the child components should not be
evaluated/rendered, avoiding the overhead.


==================================================

thanks for your reply,

but there is not rendered attribute for ui:fragment, why it
can help me?In
my case , the rendered property is very important.  i guess 
jsf  doesn't
creat these inputText instances when rendered of f:subview
is false, but not
facelets.
