Hi,
Is it possible to change the visibility of a component after page is
rendered?
Like when the page is loaded.
I tried with:
@Override
public void onAfterRender(){
super.onAfterRender();
this.myComponent.setVisible(false);
this.add(this.myComponent);
}
but i get an error:
org.apache.wicket.WicketRuntimeException: Cannot modify component hierarchy
after render phase has started (page version cant change then anymore)
any workaround?
