its not idea - but sometimes over use of eval can't be helped - only you
know the answer to that, being your domain model expert.
Well, then the optimal way is to Pre-Evaluate it in the code and assert that
variable as a Fact. But I dont think this is great from a declarative
programming point of view.
Actually in decision table, a condition will be repeated "Row" number of times.
So in the condition if an eval() is used; that eval is used "Row" number of
times (though prasctically dependson other conditions, if at runtime how many
times the eval will be used), but still it is inefficient.
I think it is important to maintain discipline when writing declarative
staements, and should try and rely less on the code for efficient solutions.
I guess I have no choice in this case.
Thanks for you reply.
