Can you give an example of differences between state saving method on client and server?

[Emily Gu]

Hi,
 What is the recommand method for

<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>

The default value is server. What can go wrong if I change it to client? I would like to use a popup frame from jenia4faces. It requires client as the saving state.

 

Thanks for your help!!
