Upon submit, if all validation went successful, each component store it's current internal in the backing bean property represented by the value expression.
If validation was unsuccessful, the form is rendered using the component's internal values In all other cases, form will render it's values depending on the current backing bean values. So unless you have validaiton error, your components always loads the most current value from your backing bean. (Up to you to have up to date values in the backing beans. Pretty easy if they are request scope) The datatable does not store value. Each time it needs to iterate over it's content, it does evaluate the backing bean collection.
