Renderer and encodeChildren

[Mario Ivankovits]

Hi!

In JSF 1.1 I am curious about the javax.faces.renderer.Renderer class in
JSF 1.1, in particular the following piece of code:

    public void encodeChildren(FacesContext context,
                               UIComponent component)
            throws IOException
    {
        if (context == null) throw new NullPointerException("context");
        if (component == null) throw new NullPointerException("component");
       
        List children = component.getChildren();
        for (int i=0; i<children.size(); i++)
        {
            UIComponent child = (UIComponent) children.get(i);
           
            if (!child.isRendered())
            {
                continue;
            }

            child.encodeBegin(context);
            if (child.getRendersChildren())
            {
                child.encodeChildren(context);
            }
            child.encodeEnd(context);
        }
    }


I wonder WHEN are the children rendered if the component returns false
on getRendersChildren here.
And how/why does it work when mixing things, lets say you have
t:div/h:panelGroup/t:div
where t:div returns false on getRendersChildren() and h:panelGroup
returns true.

Is there a simple answer to this?

Ciao,
