protected void onInitialize()
Component
Page
thus providing the component with an atomic callback
when the component's environment is built out.
Overrides must call super#Component.onInitialize()
. Usually this should be the first thing an
override does, much like a constructor.
Parent containers are guaranteed to be initialized before their children
It is safe to use Component.getPage()
in this method
NOTE:The timing of this call is not precise, the contract is that it is called sometime
before Component.onBeforeRender()
.
