Hi 1.i have a rule like this rule "Function Call" dialect "mvel" when PassThrough( $c : name) eval(($c = hello("rahul"))!=null) then System.out.println($c); end in this my function will return the string as capital and am entering to the consequence part but the $c is printed as null. am not getting what is happend. And if i want to assign the result of function call to a String declared as (String s) how can it be done -- View this message in context: http://drools.46999.n3.nabble.com/using-variables-in-eval-tp3440419p34404...
