That's first confusing point. Javadocs on
callOnBeforeRenderIfNotVisible promise us that onBeforeRender will be
called even if component is not visible, but it is a lie.
Bad, bad javadoc!

Like this?
new YourComponent(id) {
@Override
public boolean isVisible() {
return yourCondition;
}
}

That's bad because isVisible is invoked many times (50+ sometimes) per
request so no complex logic can be put there.

On Thu,
I'm trying to choose strategy for handling conditional component
visibility (and we have complex tree where many components are
conditionally visible). Overriding isVisible is bad, because many
calls. overriding onBeforeRender and callOnBeforeRender is bad,
because children visibility is
i still dont see a concrete usecase

private Boolean visible = null;
public boolean isVisible()
{
if (visible == null)
{
visible = [ put your complicated logic here];
}
return visible;
}
public void onDetach()
{
super.onDetach();
visible = null;
}
What's wrong with this?
