OK, that's a requirement, not a problem ;-)

No Problem. That makes sense.

I understand. You will have something like this:
p1: customer 1
p2: customer 1
p3: customer 1
p4: customer 2
p5: customer 2
p6: customer 3
and so on...
Still no problem.

Oops: problem! I don't understand the above sentence.

No... I still don't understand what you mean.

Now you have completely lost me.
Why don't you do this in a more simple way.
Here's some PSEUDOCODE showing how I would do it.
MyEventClass extends PdfPageEventHelper {
int pagenumber;
String customerid = "";
public void setCustomerInfo(String customerid) {
pagenumber = 0;
this.customerid = customerid;
}
public void onEndPage(...) {
pagenumber++;
// draw your header and footer using pagenumber and customerid
// but in a simpler way than in your initial code sample
...
}
}
MyMainClass {
public static void main(String[] args) {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(...);
MyEventClass event = new MyEventClass();
writer.setPageEvent(event);
document.open();
List list = getCustomerIds();
String id;
for (Iterator i = list.iterator(); i.hasNext(); ) {
id = (String) i.next();
event.setCustomerInfo(id);
document.newPage();
// add as many pages you want
}
}
public static List getCustomerIds() {
List list = new ArrayList();
// fill the list with Strings
...
return list;
}
}
There may or may not be a small problem with the header/footer
on the first page, but it's nothing you won't be able to fix.
