If you have a wrong selection, that results into "%DPL-0.9.9-ERROR: No selection criteria found", which is correct. On MW1.10 you get on Preview of the article the following error: Notice: Undefined index: id in /home/.../www/htdocs/.../includes/EditPage.php on line 1776
Sorry, sometimes you get this error also, when there are results. Preview: Does not work Saved article: Does work.
The error seems to come out of the WIKI kernel. DPL does not call EditPage.php - so it is more likely that the reason for this lies in some changes made between Mediawiki 1.9 and 1.10.
