// specified URL and calls the buildAndDisplayMenu() function upon completion of loading the IFRAME. The document
// returned by the specified URL must contain a javascript function called "getMenuContents()" which returns 
// an array. The contents of the array must be in the following format ( array[i] = <menu-item-display-name>; 
// array[i+1] = <menu-item-action-url> ). The menu is attached to an HTML element with the id equal to the 
// unique identifier. So, in the portlet context menu case, the image associated with the context menu must have
// an ID equal to the portlet window ID. The dynamically created DIV and IFRAME are deleted after the menu 
// contents are populated and the same menu is returned for the duration of the request in which it was created.
