PEAR::Pager question

Just spotted a problem when I first tried using the PEAR::Pager class. I can assign the number of pages to be listed with "totalItems" or as an array via "itemData". So far so good. For instance the "itemData"-array could look like this: $array = array("a", "b", ... , "z"); When I then build the links the class returns the pagination in the following form: http://SERVER/FILE?pageID=1 to http://SERVER/FILE?pageID=26 But I need the class to work with the values assigned by the "itemData"-array. That should look like: http://SERVER/FILE?pageID=a to http://SERVER/FILE?pageID=z Is that possible? If not the possibility to assign an array would be absolutely useless in every case, wouldn't it?
