Hello Thibault,
First let me say that I love what you done with AlivePDF, it certainly
helps me a great deal and I apologize if I am posting this as an issue but
it is for me.
I am using the PDF class to make a calendar from a Flex app. As I compose
the calendar I ran into the situation where some of the information
overflow to the next page that AlivePDF automatically creates for you in
such case.
This is great, but now as I retrieve the y coordinate, I realize that I
don't know what page the getY() pulls the info or at least I am unable to
tell the page... (the currentPage().Page property is always 0)
This is not a problem the first time around because I can see that the
totalPages property has changed, but it is if the next day has a longer
text than that one.
Below is an extract of my code, it probably will make more sense than my
blabing.
private function ProcessCalendar(columnCount:Number):void
{
var verticalY:Number;
var cellContentWidth:Number;
var verticalOffset:Number;
var offset:int;
var title:String = null;

var content:String = null;
var contentAlign:String = null;
