Partial State Saving Feature in JSF 2

Question

Can someone please explain the partial state saving feature in JSF ? I have worked with JSF 1.2 and this feature didn't exist there . I think it is new to JSF 2.0 ? What benefit do we get by partial state saving over regular state saving ?

Answer 1

It provides to less memory usage by saving just modification on bean. Default is true, you can set it on conf like below;

<context-param>
    <param-name>javax.faces.PARTIAL_STATE_SAVING</param-name>
    <param-value>false</param-value>
</context-param>
