The way I do it, is this:
protected void onBeforeRender() {
//my init code
super.onBeforeRender();
}
I think it can be documented in the javadoc, that it is mandatory to call
super at the end.
User can also have a problem if just override the onBeforeRender without
calling the super.
I think, there is a lack of another life-cycle method which would not force
user to call super. Something like the below:
protected void onBeforeRender() {
onBeforeRenderCalled()
super.onBeforeRender();
}
where
onBeforeRenderCalled()
is an empty method which would allow user to add his init logic.
