Answer 1

JSF RichFace

Never put logic into your getters.
They are called multiple times and
should only return something already
populated by another method. For
example if you are chaining drop-downs
together use an a4j:support tag on the
first one with an action attribute
that loads the data which is then
retrieved when you reRender the second
one.

Use the ajaxSingle=”true” unless
you actually want to send the whole
form back to the server.
Don’t use a
rich component if you only need a
normal one. For example don’t use
rich:dataTable unless you are making
use of some of the features that it
has over and above h:dataTable.

Consider using immediate=true
attributes on elements where you do
not need validation Avoid displaying
large tables to user.

Use pagination
Do not over complicate EL expressions,
code them in Java in backing bean
