For example you can use it in onInit() of component B:

{

ComponentA compA = (ComponentA)getCallerForm();

compA.showMessage();

}

As i understand, you want to call showMessage() method on component A from component B

In component B you'll show a message from that component, not A, most likely by callling the prompt component. If you need to display some message dynamically determined in A, then you can pass some arguments to B when calling setComponentNested.

It means that we cannot call the method of component A into component B. I know that by passing argument we can display that values in component B.But my requirement is not like that .I have to call the method of component A into Component B Is it possible if so, How ?.Can I create the reference of Component A in component B.
