Re: [Semediawiki-user] Possible bug with properties?

[Alexey D. <al...@al...>]

Hi,

I've found why property value '1' is replaced by a link to 'unrelated' 
:) page.
In the past there was the page '1'. It was moved without redirect.
Now [[1]] is shown as red link but [[propname::1] or {{#ask ... |?propname}}
shows new title instead of red link.

It can be reproduced on the latest MW (1.21.1) and SMW (1.9 alpha, git 
master)

Hope it'll help to fix this bug,
Alexey
