I downloaded DataTable2 from Sourceforge, installed it with
require_once "$IP/extensions/DataTable2/DataTable2.php";
and... nothing. The LUA console tells me:
Lua error in console ... attempt to index field 'dpl' (a nil value).
This is what I had typed in:
=mw.ext.dpl.getPagenames{ namespace = 14, text = 'Traversal' }
Is there anything else I need to do? Is DataTable2 even the same extension as DynamicPageListEngine?
