[rules-users] Adding an optional condition without using eval()

Hi, My rule template project is finally working, more-or-less. I've got 5 lines of conditions, the last 2 of which are evals. One of them compares dates, and has to be an eval(). The other though, I think I should be able to convert to non-eval DRL, but I am not sure how, because it is an optional condition. So, I've got $current:Claim(historic==false, ...) $historic:Claim(historic==true, ...) eval($current.hasSameDoctor($historic,"@{CHECK_DOCTOR}")); so, the line disappears if @{CHECK_DOCTOR} is blank, which is what I want. I want something like, eval($current.doc == $historic.doc) but i only want to check this if @{CHECK_DOCTOR} is "Y". Is there any way to do this check without an eval?
