Regis,

  If Grade.A and Grade.B are object types, try this:

...
when
customer: Customer( code == "J", gr : grade -> ( gr.equals(Grade.A) || gr.equals(Grade.B) )
then
...

  If Grade.A and Grade.B are primitive types:

...
when
customer: Customer( code == "J", gr : grade -> ( ( gr == Grade.A ) || ( gr == Grade.B ) )
then
...

  Hope it helps.

       Edson

Hi,
can someone explain me how to write the following condition :

(Customer(grade==Grade.A) or Customer(grade==Grade.B))      and   
Customer(code=="J")


the following snippet produces :

unknown:52:66 Unexpected token ')'
Unable to resolve ObjectType '('


rule "discount10"
no-loop true
   when
       #conditions
       customer:  (Customer(grade==Grade.A) or Customer(grade==Grade.B))      and   
Customer(code=="J")
       eval (customer.getTotal()>100000)
then #actions

end
