Provide a method to initialise a component
------------------------------------------
Key: WICKET-1674
URL: https://issues.apache.org/jira/browse/WICKET-1674
Project: Wicket
Issue Type: New Feature
Components: wicket
Affects Versions: 1.4-M1
Reporter: John Patterson
Normally components are initialised in the constructor which does not allow for
use of factory methods that need to access state. This problem was present in
the PagingNavigator. Problem detailed here:
http://www.nabble.com/Re%3A-Alternative-method-to-initialise-page-p16742891.html
The current solution is to use onBeforeRender() but this is called more than
once so care need to be taken to not re-add children and super.onBeforeRender
must be called.
To ease creating extendable components I think it was decided worth using a
flag bit:

and creating some hook onBeforeFirstRender or onFirstRender or something like
that.
