[Yannick <yannick@xxxxxxxxxxxxxxxx>]

Hi,

I don't think the problem is the one you described because in case 1)
the rules' overriding is appropriate.

The problem only appears when I separate the "call" to the rule's name
and the rules with different context.


Anyways, thanks for your reply, it reminded me I didn't check the bugzilla.
