Hi Rolf,

If each page is a subelement, you can just check the size of the array returned by $element->get_containers($page_element_key_name).
So:
my $pagecount = scalar($element->get_containers($page_element_key_name));
> Another question to set_burn_again:
> As far as I understand this function, i could split a list of N "whatever" to be displayed in chunks of n whatever on several pages.
> Is there a way where I can get the "counter", which page i'm currently burning or do I have to store in in burner->notes and increment it myself ?
The value returned by $burner->get_page() is the number of the current
page minus one. So it's false on page 1, and a positive integer for all
other pages
Hope this helps,
Bret
