I played a bit with my local installation of SMW 1.2 and SMWsvn and noticed a bug : Inline queries don't refresh after the deletion of a property.

Here is the basic scenario : (This behavior can be reproduced on the sandbox http://sandbox.semantic-mediawiki.org/wiki/Testpage )
- Add properties to pages
   in my example : [[check::1]] for Page1check and [[check::2]] for Page2check
- add a query for these properties to a page
   for me : {{#ask: [[check::+]]}} on Testpage
- remove one property from one of the first pages
   let's remove [[check::1]] on Page1check
- The page with the query still displays the erased property unless you re-edit it.

I'm sure this behaviour didn't exist in SMW 1.1.2.
I wanted to raise this issue on the list, because if you can confirm, this should be corrected as soon as possible.
