D2W Rule Question

All:

I’ve got a rule that looks like this:

110 : ((entity.name = 'PTAMembership') or (entity.name = 'PTAMember')) => isEntityEditable = true [com.webobjects.directtoweb.BooleanAssignment ]

Is anyone able to tell me what I'm doing wrong with this rule? At application launch this is causing an error like:

IllegalArgumentException: ** DirectToWeb exception - a rule cannot be instantiated if its right hand side is null. LHS=((entity.name = 'PTAMembership') or (entity.name = 'PTAMember'))  RHS=null

I could swear I’ve had this rule in there for a long time and it just recently started to throw exceptions - but I’ve been known to be very wrong. :-)
