They have a relatively simple expression syntax that only supports binary logical expressions (although, without too much trouble, adding right- or left-associativity for logical operators isn't really that tough, and most programmers expect that kind of thing). So, instead, you have to do this: (A or B) or C Looking at your "it doesn't work" scenario, you have the situation above that I mentioned if you just call this "A": ((oldProductStatusId == 21) and ( (productStatusId == 21) or (productStatusId == 23))) and this "B": ((oldProductStatusId == 23) and ( (productStatusId == 23) or (productStatusId == 22))) or and this "C": ((oldProductStatusId == 23) and ( (productStatusId == 23) or (productStatusId == 22))) You need to wrap your first two logical combinations in yet another set of parenthesis.
