I use MediaWiki-1.10.1 and SMW-.0.7
I'm using relations with namespaces and I find the following problems:
1-If I define two relations Rel1 and A:Rel1 then, in the factbox of a page containing both relations, the relations are collapsed in only one relation, Rel1.
2-Furthermore, if I click on Rel1, in the factBox, then I see the page of Rel1 that has no references to the related terms, so it seems not complete and correct.
