Re: [rules-users] or condition - subrules

This would certainly work, but you should evaluate the performance carefully. This is a cartesian join, and will run the eval() statement (number of CoApplicant objects) * (number of Contract objects) on startup, (number of CoApplicant objects) times when ANY Contract changes or is asserted, an

Re: [rules-users] or condition - subrules
