I have a defrule like this: ( ... => ... (bind ?objVal (get ?obj property)) ...
) I need to make sure that ?objVal is not nill before proceeding further. I don't see any functions that might help me here. (if (eq ..)) doesn't work since it's going to try to call Object.equals(). There are a few calls prior to the bind that dont lend themselves to sitting on the LHS. Any ideas ? -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)
