I read this article and my first approach was like
"If an outside component controls another’s visibility the best way is
to override the controlling component’s onConfigure() and call
controlled.setVisible()"
But this doesnt worked, because onConfigure() of my RadioChoice runs
only once.
What I can do to force onConfigure() of RadioChoice again is, also
adding it to the AjaxRequestTarget.
r.add(new AjaxFormChoiceComponentUpdatingBehavior(){
@Override
protected void onUpdate(AjaxRequestTarget target) {
-> target.add(r);
target.add(wmc);
}
}
This works, too...
I am not sure now, whats the better way... *lol*
Determine "my" visibility in my onConfigure() by watching the state of
the controller by myself, and adding only one object to the
AjaxRequestTarget.
or
Let set the visibility of "me" by a controller and adding two objects to
the AjaxRequestTarget, so the onConfigure() of the controller can do its
visibility setting job.
Pull or Push?
regards
Patrick
