Lazy loading Accordion content

[Edvin Syse]

My Pivot App uses JDK ServiceLoader to load "modules" for an Accordion. 
Some of the modules will pull data from a remote server and do some 
initialization when created so I want to do it when each panel is shown 
for the first time.

I want to check if my approach is viable: Most Panels are ScrollPanes, 
and they are ofcourse unexpensive to create. I then override the 
layout() method and to something like:

    protected void layout() {
        if (!initialized) {
            setColumnHeader(createColumnHeader());
            setView(createView());
            initialized = true;
        }
        super.layout();
    }

This seems to work, but is it an OK approach?
