Background
With the deprecation of stateful pages we need a way to preserve control state across requests.
Proposal
Add a new interface that stateful controls can implement:
Stateful.java
interface Stateful { public void saveState(Page page, Context context) // public void saveState(Page page, Context context, Map options)?? // By default save in session under its name+page path // This method can call getState to retrieve this components state // Optimization includes GZIP compressing the state public void restoreState(Page page, Context context) //public void restoreState(Page page, Context context, Map options)?? // Grab state from session and invoke setState public Object getState() { // Assemble state and return as object. This allows developers to save state in cookie instead .If this control is a container it should assemble all its child control state } public void setState(Object state) { // Cast object back to its type and set state to this control and its children } public String getStateAsString() { // Return a user friendly presentation of the state }
