Not sure why do you want to do that. Better would be to simply:
rule "Your 5 Rule"
dialect "mvel"
when
$l:ArrayList( this contains "test" )
then
#actions
System.out.println("OK");
end
If you want to do that inside an eval, MVEL does not have "memberOf"
operator, but it has "contains", so just write:
eval( $l contains "test" )

Hi,
I want to use the keyword memberOf in an eval statement (with dialect =
mvel).
rule "Your 5 Rule"
dialect "mvel"
when
$l:ArrayList()
eval("test" memberOf $l)
then
#actions
System.out.println("OK");
end
but it doesn't work, and I don't understand the error :
Caused by: java.lang.ClassCastException: java.lang.String
at
org.drools.base.mvel.MVELEvalExpression.evaluate(MVELEvalExpression.java
:36)
at org.drools.rule.EvalCondition.isAllowed(EvalCondition.java:72)
... 12 more
Thanks for your help,
V.
