public void pageBeginRender(PageEvent
event){
recorderLocked = true;
}
public
void pageEndRender(PageEvent event){
recorderLocked =
false;
}
The above is render listener's mothod. The listener
is added to the page in finishLoad(). In component java code,
fireObservedChange() is invoked if recorderLocked is true, otherwise this
mothod is not invoked.
When I click the page for the first time, an exception
that indicates some states were not been persistented is
thrown.
What's wrong with my code?

Page recorders are locked after the page
begins rendering a real response. You must ensure that no changes
occur to persistent properties after this point. Use the
PageRenderListener events to know when a render is about to
start.

The above is throwned exception when the fireObservedChange() is

exception?

A component can invoke
fireObservedChange() just like a page can.
However, components don't have the
equivalent of detach().
Instead, they must implement interface
PageDetachListener and implement method finishLoad() to register as a
listener with the page.

Hi there,
How to develope a component which can persistent
its state by itself?
I have refer the Persistent Component State in
Chapter 5 of Developer's Guide, but the component seems to lost
its state.
How to do?
Thanks.
