Well, you don't want to store onceInitialized as a persistent
property, at least not within the context of how I am using it. It
doesn't mean that the page will only be initialized once per
user-session. It just means that it will be initialized only once per
http request, even if there is both a rewind and a render cycle. So
my annotation is @InitialValue("ognl:false") which causes it to be
reset every time the page comes out of the cache for use.

In the code u write there are two method "isOnceInitialized()" and
"setOnceInitialized()" . So i think there should have a property
"onceInitialized" for this.For example:
@Persist("client")
public abstract boolean isOnceInitialized();
public abstract void setOnceInitialized(boolean b);
.......
Am i right???
Thank u very much!!!
