ws.addEventListener("fault",faultHandler);
ws.getMostPopularPosts();
ws.loadWSDL();
ws.getMostPopularPosts.send();

Answer 1

The request object is an object and you are trying to
populate it with XML. Try somethng like this:
var oRequest:Object = {daysBack:30,limit:5}; //of course the
values can be variables
ws.getMostPopularPosts.request = oRequest;
