getting object fron its container

[Aanjaneya Shukla]

Hi,
I am having some issues using 'getNamedComponent' method.

BXML file:
<PushButton bxml:id="Button1" buttonData="%Button1"/>

Java file:
PushButton Button1 = (PushButton)window.getNamedComponent("Button1");

I want to get Button object but I have getting null value returned.
