Problem

There are lots of projects with universities in my wiki-db, connected with categories like "dep03", "Wien TU", "Regensburg U" and "project-id" and containing project-descriptions. When I use "*universities" and "dep03" as page-selectors (namespace=category) I don´t get a list of universities which are only connected with department 03. Why?--Hannds 0920 15:40, 20 September 2009 (UTC)

I think there will be some logical reason for this - either a bug in DPL or a problem on your side. I recommend to reproduce your problem here in this wiki with some sample data. I am quite confident that we will find out the cause.

BTW: The "*" - operator only searches one level deep in the cat tree, "**" goes two levels deep (more is not possible atm.)

You can use pseudo-recursion to traverse deeper trees as is shown in some examples on this web site.

With these lines I solved my basic problem .. <noinclude><dpl></noinclude>

 category=+*universities
 category=-dep03
 category=-projects current
 ordermethod=category,sortkey
 headingmode=ordered
 include=#..some sections..

<noinclude></dpl></noinclude> .. but without being completely content. For example because there appeared out of the resulting list a new question - after about 400 lines (presenting 130 institutions) there was a break, a cut without any error message. Please, tell me how to debug effficiently dpl-errors. --Hannds 0920 22:16, 3 October 2009 (UTC)
