Hello Luka,
The action event and the value change event don't happen on the same
component, therefore they are not at the same place in the tree (obviously).
However, a side effect of that is that one of them might be in a
NamingContainer which alter its id by adding a prefix to it. See
http://java.sun.com/javaee/javaserverfaces/1.1_01/docs/api/javax/faces/component/UIComponent.html#findComponent(java.lang.String)for
the complete algorithm used in find.
Regards,
~ Simon

Hi Srinath ,
tnx for the tip. It works. Thanx again.
Still I don't understand why
event.getComponent.findComponent("someID") works under ValueChangeEvent,
but under ActionEvent it returns null.
