I guess I succeeded with your hint using following rule:

rule "Test some counting"

      no-loop true

      when

  &nb sp;         customer : Customer()

            $i : Number( intValue > 5 )

          from accumulate( $t : Ticket(status == "Escalate", customer == customer ), count( $t ))            

      then

     ;  System.out.println( "Num : " + $i + " " + customer );

end

This there any way to get access to the counted Tickets in the "then" part? Do I have to perfrom a query?

look at hte Shopping Example, I use sum() there, but the concept is the same:

rule "determine 10% discount if total purcahses is over 100"           
    no-loop true   
    when
  &n bsp;     $c : Customer()
        $i : Double(doubleValue  > 100) from accumulate ( Purchase( customer == $c, $price : product.price ),
                                                                    sum( $price ) )
    then
          $c.setDiscount( 10 );
        insertLogical( new Discount($c, 10) );   
end

Does anybody have a good example about using count()?
