This page is called by a XmlHttpRequest object. It requires parameters "page" and "macro":
|
|
they are used to call the macro that will render the HTML chunk to be returned to the browser.
|
|
It can also have a parameter "action", that refers to a method that will be triggered on
|
|
contextObj before returning the result of the macro to the browser.
