Hi,

I discovered a serious issue while playing with n-ary relations... I suspect
it's a bug in SMW.

I simply changed

Property:Instant messenger
 == Type ==
 [[Has type::String; String]]

to

Property:Instant messenger
 == Type ==
 [[Has type::String]]

and since then I get blank pages whenever I try to access a page where this
property is being used. Apache's error log contains messages like this:

[Thu Sep 25 06:20:54 2008] [error] [client 192.168.0.117] PHP Fatal error:
Call to undefined method SMWStringValue::setDVs() in
/path/wiki-experimental/extensions/SemanticMediaWiki/includes/storage/SMW_SQLStore2.php
on line 270

When I change the property back to n-ary, I can access the pages again.

Patrick.
