Stephane Cachat commented on HHH-2647:
--------------------------------------

I have the same problem in my application, and I think that is is exactly the same bug as  	 HHH-377, which was agains core 3.01

@Nicolas 
please note that precedence is not a correct answer, as (A OR B) AND C is not the same as A OR B AND C

This is a bug.
