I'm having a hard time understanding the syntax in the conditional or
left hand side of the DRL. Is it acceptable to use dot notation in
the LHS? Is there a better way to compare fields on different objects?
In the example below, I get an error "Unable to find class $d1. What
limitations are there syntactically on the left hand side? Any help
would be greatly appreciated. I have looked at all the examples and
have googled the problem and don't seem to find the answer.
*package* com.rules
#list any import classes here.
*import* com.validate.Date1
*import* com.validate.Date2
*import* java.util.Date
#declare any global variables here
*rule* "Your First Rule"
*when*
$d1 : Date1()
$d2 : Date2()
$d2 : Date2(beginDate > $d1.getEndDate)
*then*
#actions
System.out.println("do something");
*end*
