[rules-users] How to set drools.dialect.mvel.strict = false?

[Jeet Singh]

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.
