Rendered Vs Visible


RENDERED: Making a field attribute's property RENDERED as false (Rendered=false) does NOT make the component to be part of JSF Tree.

VISIBLE: Making a field attribute's property VISIBLE as false (Visible =false) make the component to be part of JSF Tree, is sent to the client as part of HTML and is HIDDEN.
