what is binding doing internally? How it will affect the normal life-cycle of JSF page? where and when should I use it? Example: I have 5 JSF components in my page. On some action...I need to set some properties of those components from the backing bean. now...if I am doing with the scope request and using binding...i can set all the properties of all the components of that page. or...with session scope and without binding i can do the same. which one is the better approach? Is it good idea to keep all the states of all components stored in session??? or bindind could be the good alternative???

Using backing bean can sometimes be abused and mix the business data with the form components, but it has its uses like it is sometimes necessary for event handlers or validators to have access to the actual components on a form. That case, yes backing beans can be used, but in general try to use a different beans for business objects.
