sure the draw() method is the first which is called before any response has been done. init(), main() and callback() need to be implemented within the page.
init() is always called first and allows preperation before any content is written to the response e.g. security checks and stuff which is necessary for main() and callback() should be placed into the init(). After the init whether main() or callback() is called.
They are never called both within one page execution. main() = common state for the page which shows the user's presentation callback() = handles all client requests callback() needs to be defined with an parameter which holds the actual action to perform.
