The original grammar specification for BooleanPredicate consists of 5 different subrules. That grammar assumes ANTLR 4. However, XText only supports ANTLR 3, which means that the original grammar causes problems. As a temporary fix, 2 of the choices (SetComparePredicate and SetMembershipPredicate) have been commented out. Eventually, they need to be uncommented and the grammar adjusted so that it works with ANTLR 3.
