Alright, I kinda found out the cause of the exception I am getting, however
I am still struggling the reason behind the exception.
So DRL_1, this works perfectly fine.
package drools;
import drools.ProposalLight;
import function drools.DateUtil.compareDatesWithTime;
rule "Date Rule"
when
$obj : ProposalLight(eval(compareDatesWithTime(endDateTime, -2, 6,
\"<\")))
then
$obj.addFailedRule("Date Rule");
end;
DRL_2, this doesn't work. and throws [Error: unable to resolve method using
strict-mode: myObject.eval(boolean)] [Near : {...
(eval(compareDatesWithTime(star ....}] ...
package drools;
import drools.ProposalLight;
import function drools.DateUtil.compareDatesWithTime;
rule "Date Rule"
when
$obj : ProposalLight(*(*eval(compareDatesWithTime(endDateTime, -2, 6,
\"<\"))*)*)
then
$obj.addFailedRule("Date Rule");
end;
Notice that extra paranthesis around eval(). This is where Drools 5.5
throws exception. Can someone please explain why this extra paranthesis
throws exception and how can I make it work.
Thanks,
Jeetendra.

The error message suggests that you have made a syntactic error in a
rule which is not the one you have posted, or you have modified the
rule too much to be of any help. Post again, taking great care not to
omit anything or to change the cause of the problem. Also, indicate
precisely the declaration of the function compareDatesWithTime().
