[rules-users] Greater than or less than in eval

[Mohod, Akash]

Just saw this mail .  My case was a slightly different.  The Double there is one that we use in Mvel as in when we do something like

$age : Double () from accumulate ( )

I was using this to compare with double in java .  Hope this is clear.

Regards,
Akash

Double as in java.lang.Double? This would be strange, since these types sure are compatible.

Thanks Wolfgang. Good spot there. The data types were not matching . Fixed now.
One of them was double and other was Double.

Space after "$"?

Error message?

Types of Employee.age, Event.ageLimit?

It would be preferable to to use
when
                Employee ($name : name, $age : age)
                Event ($eventName : eventName, ageLimit > $age)
then

Hi,

I am trying to write the following rule using Drools 5.1 but having issues.

when
                Employee ($name : name, $ age : age)
                Event ($eventName : eventName , $ageLimit : ageLimit)
                eval($age < $ ageLimit)
then
                System.out.println (" Can participate in the event ");
end


The rule fails to compile.

Regards,
Akash
