Hi experts,

I am trying to pass parameters in "when", something like

when
            $c: Cart($d.memberLevel != null &&
                  $c.alreadyApplied("my_disc") == false
                  )
and it does not want to compile on the last line. So if it is not a simple bean property, but it is depending on something, how do I express this?

Thank you.

you may want to write a function and call that i n the when clause!

for e.g.,

eval( isMemberValid( $d ) && isAlreadyApplied( $c ) )
